I'm not sure I agree that this is useful, but personally I wouldn't be
opposed to adding this if the code is simple.

I don't think it's hard to do, you just need to add a new <th> element
in cgit_print_log() and then write the <tr> element in print_commit(),
making sure that columns is also adjusted.  All of the code should be in
ui-log.c unless you add a config switch to enable this feature..
