Prior to d38379e (make update-server-info more robust,
2014-09-13), we used a straight "fopen" to create the
info/refs and objects/info/packs files, which creates the
file using mode 0666 (less the default umask).
In d38379e, we switched to creating the file with mkstemp
to get a unique filename. But mkstemp also uses the more
restrictive 0600 mode to create the file. This was an
unintended side effect that we did not want, and causes
problems when the repository is served by a different user
than the one running update-server-info (it is no longer
readable by a dumb http server running as `www`, for
example).
We can fix this by using git_mkstemp_mode and specifying
0666. Note that we could also say "just use
core.sharedrepository", as we do call adjust_shared_perm
on the result before renaming it into place. But that is
not very friendly. The shared-repo config is usually about
making things _writable_ for other users. Until d38379e,
there was no explicit config needed to serve an otherwise
readable repository, and we should consider it a
regression.
