[PATCH] Fix for config file section parsing.

Currently, if the target key has a section that matches the initial substring of another section we mistakenly believe we've found the correct section. To avoid this problem, ensure that the section lengths are identical before comparison.

Here's an example of the problem:

$ git repo-config a.b.c d
$ cat .git/config
[a.b]
        c = d
$ git repo-config a.x y
$ cat .git/config
[a.b]
        c = d
        x = y
