Display error message when commit fails (due to pre-commit hook)

If a pre-commit hook is used, edits on the website may fail. When this is the case, the page simply doesn't update on “Save”, but it is not made clear to the person who tried to edit the page. Could gitit check the return code of the commit action (I'm not sure exactly how gitit performs the commit)

Ideally, the output of the pre-commit hook should be displayed (if any) along with a failure notice (if the exit code is not 0). Alternatively, a simple, generic error message would already be useful.

Should I look into adding this feature? Would that better be handled as a plugin? (Would a plugin have access to all the same info as a git hook?)
