You can trigger a segfault in git.git by doing:
git for-each-ref --format='%(taggeremail)' refs/tags/v0.99
The v0.99 tag is special in that it contains no "tagger"
header.
The bug is obvious in copy_email, which carefully checks to
make sure the result of a strchr is non-NULL, but only after
already having used it to perform other work. The fix is to
move the check up.

Right now we pass two different pathnames ('path' and 'base') down to
read_directory_recursive(), and the only real reason for that is that we
want to allow an empty 'base' parameter, but when we do so, we need the
pathname to "opendir()" to be "." rather than the empty string.
And rather than handle that confusion in the caller, we can just fix
read_directory_recursive() to handle the case of an empty path itself,
by just passing opendir() a "." ourselves if the path is empty.
This would allow us to then drop one of the pathnames entirely from the
calling convention, but rather than do that, we'll start separating them
out as a "filesystem pathname" (the one we use for filesystem accesses)
and a "git internal base name" (which is the name that we use for git
internally).
That will eventually allow us to do things like handle different
encodings (eg the filesystem pathnames might be Latin1, while git itself
would use UTF-8 for filename information).

Introduce GIT_PS1_DESCRIBE option you can set to "contains", "branch", or
"describe" to tweak the way how a detached HEAD is described.
The default behaviour is to describe only exact match with some tag
(otherwise use the first 7 hexdigits) as before.

As I very often work on a detached HEAD, I found it pretty confusing
when __git_ps1() said 'some-name'. Did I create a branch with that name
by mistake, or do I happen to be on a commit with that exact tag?
This patch fixes the issue by enclosing non branch names in a pair of
parentheses when used to substitute %s token in __git_ps1() argument.
It also fixes a small bug where the branch part is left empty when
.git/HEAD is unreadable for whatever reason. The output now says
"(unknown)".

If your merge stops in a conflict while on a detached HEAD, recent
completion code fails to show anything. This was because various cases
added to support the operation-in-progress markers (e.g. REBASE, MERGING)
forgot that they need to set the variable "b" to something for the result
they computed to be displayed at all.
Probably not many people make trial merges on a detached HEAD (which is
tremendously useful feature of git, by the way), and that may be why this
was not noticed for a long time.

The logic in 83ae209 (checkout branch: prime cache-tree fully,

Some versions of sed exit non-zero if the file they are supplied is not
