Merge branch 'dm/run-command-ignored-hook-advise'

A hook script that is set unexecutable is simply ignored.  Git
notifies when such a file is ignored, unless the message is
squelched via advice.ignoredHook configuration.

* dm/run-command-ignored-hook-advise:
run-command: add hint when a hook is ignored
