[PATCH v3] Gitweb: Use a default for a bad env config file variable

[James Shubin <purpleidea@xxxxxxxxx>]

It's quite trivial really, all that changes is that if someone sets
the environment variable: $GITWEB_CONFIG_SYSTEM, and this points to
something like: /srv/gitosis/gitweb.conf, which doesn't actually
exist, then gitweb will default to trying out the built in default of
/etc/gitweb.conf (if it was built with that value).

This patch should make it easier for people who are configuring
gitweb+gitosis, so that a separate gitweb.conf config file can be used
to call the main config, but which doesn't null out the system
defaults if it is missing.

PS: thanks to everyone for their patience with my first patch.
This applied cleanly with git am, let me know if I should do anything
else differently.

Not really, no. You should send the patches you produce with
git-format-patch with git-send-email, and try sending to yourself
first and apply it with git-am (this is all mentioned in
SubmittingPatches).

This is what your new patch looks like after being applied with
git-am:

    commit 7be6207e8923cd7c4c48243f5257a0fdba6bfa0a

        Use a default for a bad env config file variable

        Sorry about that,
        I guess I had only read the README.
        Hope this is better:

I.e. your message has become part of the patch. To include commentary
on resend add it after -- and before the diffstat (also in
SubmittingPatches).

Thanks.
