And as for bash, only gitdiff-do and gitlog.sh 'explicitly' use bash instead of /bin/sh. On most Linux distros, /bin/sh is just a symbolic link to bash. But not on some others. I found gitlsobj.sh could not work using a plain /bin/sh on fbsd. To make life easier, i think it might be better if we all explicitly use bash for all shell scripts.

patch below assumes the patch above has been applied.

Explicitly use bash #!/bin/sh ==> #!/usr/bin/env bash
