[PATCH] rebase -i: fix has_action

[Noe Rubinstein <nrubinstein@proformatique.com>]

When doing git rebase -i, removing all actions in the todo list is
supposed to result in aborting the rebase. However, if there are spaces
at the beginning of an empty line, has_action returns true and the
rebase therefore removes all commits. This is probably not what a user
leaving a space on an empty line expects.

This patch fixes the bug by changing has_action to grep any line
containing anything that is not a space nor a #.
