Jeff King f445644fd2 run-command: optimize out useless shell calls ...

If there are no metacharacters in the program to be run, we
can just skip running the shell entirely and directly exec
the program.

The metacharacter test is pulled verbatim from
launch_editor, which already implements this optimization.
