[PATCH 1/1] run-command.c: ignore bad permissions on dirs in PATH

[Dale Rowley <ddrowley@gmail.com>]

All of my git aliases stopped working one day. For example, when I ran 'git ci'
(where 'ci' is an alias for 'commit') it printed out this error:

fatal: cannot exec 'git-ci': Permission denied

This error was confusing (I didn't have a 'git-ci' executable anywhere, so why
was it complaining about permissions?) and it took me a while to figure out that
this was happening because I happened to have a random directory in my PATH that
had permissions set incorrectly. Git should probably ignore this, and here is
one way to fix it, although I'm not sure if it's the best way.
