I squashed the two commits together and I also used Jakub's idea to
create a wrapper for git_get_head_hash.

Make things nicer in cases when you hand craft the snapshot URL but
make a typo in defining the hash variable (e.g. netx instead of next);
you will now get an error message instead of a broken tarball.
To maintain backwards compatibility, git_get_head_hash is now a wrapper
for git_get_full_hash, as suggested by Jakub Narebski.
Tests for t9501 are included to demonstrate changed functionality.
