[PATCH 2/2] git-gui - provide commit-type to the hooks/pre-commit script

If hooks/pre-commit acts based upon the changes to be checked in
rather than just the resulting content, the script needs to know which
commit to use. For a normal commit, this is HEAD, but when amending this
is HEAD~1. So, this modifies commit.c to pass $1 as normal|amend depending
upon the commit type. Existing scripts are unaffected as they did not
expect any argument so will silently ignore this extra bit of info.
