I'll leave out the "some legacy shells we do not support want to use
`command`" from the justification of this change.  Use of the
write_script helper is the right thing to do---$SHELL_PATH points at
the shell the user told us s/he wants to use, and that is a reason
enough for this change.  The reason why the user wants to use that
shell is immaterial.

Thanks.
