When you have a non-directory on your PATH, a funny thing happens: $ PATH=$PATH:/bin/sh git foo fatal: cannot exec 'git-foo': Not a directory?
Worse yet, as real commands always take precedence over aliases, this behaviour interacts rather badly with them: $ PATH=$PATH:/bin/sh git -c alias.foo=show git foo -s fatal: cannot exec 'git-foo': Not a directory? This is because an ENOTDIR error from the underlying execvp(2) is reported back to the caller of our sane_execvp() wrapper as-is. By translating it to ENOENT, just like the case where we _might_ have the command in an unreadable directory, fixes it. Without an alias, we would get git: 'foo' is not a git command. See 'git --help'. and we use the 'foo' alias when it is available.
