[PATCH] Use "git_config_string" to simplify "builtin-gc.c" code where "prune_expire" is set

[David Bryson]

Hi all,
This is a quick janitor patch and my first patch sent to the git mailing
list.  Please let me know if I have done any process of the patch
submission wrong, and if I got the Janitorial task done in the proper
fashion.

This part of the message probably should go after the "---" line.
Everything above "---" goes into the commit message, everything
after it is automatically cut by git-am.

This sort of "Hi, I'm new" isn't very useful in the long term in
the project logs, but its still useful to introduce yourself.  ;-)

The message formatting was a lot better.  But:

builtin-gc.c:65: warning: passing argument 1 of 'git_config_string' from incompatible pointer type

>From http://git.or.cz/gitwiki/Janitor:

  This is because the first argument to "git_config_string" should
  be a "const char **", not a "char **". There will be a compile
  time warning if a "char **" is passed instead of a "const char **"
  and the patch will be rejected. (And no, casting the "char **"
  into a "const char **" is not a good solution either.)"

Manage to fix the const char ** compile error, third time is a
harm(hopefully!)
