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

That is, when you write a new git command and forget to set execute
permission, you lose the "Permission denied" error. (Ditto if you
accidentally remove execute permission from an existing external git command.)

True, but after getting the warning that 'git-frob' doesn't exist, it
would probably only take a minute to figure out that 'git-frob'
permissions need to be fixed, and then it's understandable why git
choked on it. In contrast, it took me a while to discover my PATH
permissions problem, and even then it wasn't clear why git should die
because of a permissions problem on a directory that had little to do
with git.
