This fixes the case where an untracked symlink that points at a directory
with tracked paths confuses the checkout logic, demostrated in t6035.

longest_path_match() in symlinks.c does exactly what it's name says,
but in some cases that match can be too long, since the
has_*_leading_path() functions assumes that the match will newer be as
long as the name string given to the function.
fix this by adding an extra if test which checks if the match length
is equal to the 'len' parameter.

This test creates two directories, a/b and a/b-2, then replaces a/b with
a symlink to a/b-2, then merges that change into the 'baseline' commit,
which contains an unrelated change.
There are two bugs:
1. 'git checkout' incorrectly deletes work tree file a/b-2/d.
2. 'git merge' incorrectly deletes work tree file a/b-2/d.
The test goes on to create another branch in which a/b-2 is replaced
with a symlink to a/b (i.e., the reverse of what was done the first
time), and merge it into the 'baseline' commit.
There is a different bug:
3. The merge should be clean, but git reports a conflict.
