"git add *" is actually fundamentally different from "git add .", and
yeah, you should generally use the latter.
The reason? The argument list is actually something different from what
you think it is. For git, it's a "pathspec", so what actualy happens is
that in *both* cases, it will really traverse the whole tree, and then
match every file it finds against the pathspec.
So think of the arguments not as a file list, but as a random bunch of
patterns to match against the files you have!
Which is why the cost is actually approximately O(n*m), where "n" is the
size of the working tree, and "m" is the number of pathspecs.
So the reason "git add ." is fast is actually that "m" in that case is
just 1 (just one trivial pattern), and then "git add *" is slow because
"m" is large (lots of complicated patterns). In both cases, 'n' is the
same (== the whole set of files in your working tree).
Anyway, here's a trivial patch that doesn't change this fundamental fact,
but that avoids doing anything *expensive* until we've done some cheap
initial tests. It may or may not help your test-case, but it's pretty
simple and it matches the other git optimizations in this area (ie
"conceptually handle the general case, but optimize the simple cases where
we can exit early")
Notice how this patch doesn' actually change the fundamental O(n^2)
behaviour, but it makes it much cheaper by generally avoiding the
expensive 'fnmatch' and 'strlen/strncmp' when they are obviously not
needed.

This makes a struct ref able to represent a symref, and makes http.c

This simplifies a few things, makes a few things slightly more
complicated, but, more importantly, allows that, when struct ref can
represent a symref, http_fetch_ref() can return one.
Incidentally makes the string that http_fetch_ref() gets include "refs/"
(if appropriate), because that's how the name field of struct ref works.
As far as I can tell, the usage in walker:interpret_target() wouldn't have
worked previously, if it ever would have been used, which it wouldn't
(since the fetch process uses the hash instead of the name of the ref
there).

Currently "git help -m GITCMD" is restricted to a set of man viewers
defined at compile time. You can subvert the "man.<tool>.path" to
force "git help -m" to use a different man, viewer, but if you have a
man viewer whose invocation syntax does not match one of the current
tools then you would have to write a wrapper script for it.
This patch adds a git config variable "man.<tool>.cmd" which allows a
more flexible man viewer choice.
If you run "git help -m GITCMD" with the "man.viewer" config variable
set to an unrecognized tool then it will query the "man.<tool>.cmd"
config variable. If this variable exists, then the specified tool will
be treated as a custom man viewer and it will be run in a shell with
the man page name of the GITCMD added as extra parameter.

This moves the scanning of the argument list for each view into a
new function, parseviewargs, which is called from start_rev_list.
This also makes the date mode and the merge mode be per-view rather
than global. In merge mode, we work out the list of relevant files
in a new function called from start_rev_list, so it will be updated
on File->Reload. Plus we now do that after running the argscmd, so
if we have one and it generates a -d or --merge option they will be
correctly handled now.
The other thing this does is to make errors detected in start_rev_list
not be fatal. Now instead of doing exit 1 we just pop up and error
window and put "No commits selected" in the graph pane.

Since git-remote always uses remote tracking branches, it

I.e., we should generate

Previously, a push like:
git push remote src:dst
would go through the following steps:
1. check for an unambiguous 'dst' on the remote; if it
exists, then push to that ref
2. otherwise, check if 'dst' begins with 'refs/'; if it
does, create a new ref
3. otherwise, complain because we don't know where in the
refs hierarchy to put 'dst'
However, in some cases, we can guess about the ref type of
'dst' based on the ref type of 'src'. Specifically, before
complaining we now check:
2.5. if 'src' resolves to a ref starting with refs/heads
or refs/tags, then prepend that to 'dst'
So now this creates a new branch on the remote, whereas it
previously failed with an error message:
git push master:newbranch
Note that, by design, we limit this DWIM behavior only to
source refs which resolve exactly (including symrefs which
resolve to existing refs). We still complain on a partial
destination refspec if the source is a raw sha1, or a ref
expression such as 'master~10'.

This test tried to push into a remote with ambiguous refs in
remotes/$x/master and remotes/$y/master. However, the remote
never actually tells us about the refs/remotes hierarchy, so
we don't even see this ambiguity.
The test happened to pass because we were simply looking for
failure, and the test fails for another reason: the dst
refspec does not exist and does not begin with refs/, making
it invalid.

According to the similar patch from David Kågedal [1], "this will make
it a little less posix-dependent and more efficient." However, there
are two other areas that need to replaced, namely
git-run-command-region and git-run-hooks. This patch implements the
changes of [1] onto those Emacs Lisp functions.
If unpatched, using the git port "msysgit" on Windows will require
defadvice changes as shown at [2] (also explained at 4msysgit.git
[3]).
I have tested git-run-command-region on msysgit, because this is
always called by git-commit (via git-commit-tree <- git-do-commit <-
git-commit-file). However, I could not test git-run-hooks because it
currently does not work on the Emacs Windows port. The latter reports
the hooks files as a+rw and a-x, despite msysgit and cygwin chmod
setting on the respective files.

These options filter the output from git branch to only include branches
whose tip is either merged or not merged into HEAD.
The use-case for these options is when working with integration of branches
from many remotes: `git branch --no-merged -a` will show a nice list of merge
candidates while `git branch --merged -a` will show the progress of your
integration work.
Also, a plain `git branch --merged` is a quick way to find local branches
which you might want to delete.
