In terms of formatting the patch, I see no problems with your
submission.

My problem is more a conceptual one: it is not trivial to replace
/bin/sh with any other shell, because they work differently.  The
command in question builds a complex shell command to run, and it
isn't obvious that any user shell will be able to run it.

OTOH, every Posix system I know about does have /bin/sh, so I'm
curious what kind of system did you see where /bin/sh is absent.

And finally, I don't think I understand the issue with .bashrc etc.:
if you launch /bin/sh, it is not supposed to process these init files,
they are processed by bash, zsh, and other shells.

Could you please elaborate on the specific problems you had and tell
more about your system configuration where you bumped into these
problems?

Thanks.
