} Sorry, I missed that.  Anyway, this does not work for me for some

Probably because you need to "set complete".  I should have mentioned that.

} I am most grateful to the people who wrote and maintain mush.  Still,
} I don't see why invoking an additional process, after checking whether
} $folder exists, constitutes a problem.

It "constitutes a problem" because Mush itself can't do things like
the `echo ...` I mentioned -- there is no direct way to interpolate
*textual* command output into a mush command line; mush deals strictly
with message lists for purposes of `` and pipes.

} Better yet, I think it might be a good idea to add some mechanism
} to mush, allowing the user to convert the string +something to 
} $folder/something.  People may want to do extra-mush stuff other
} than zfolder with folders.

What could be done is to have the "sh" command expand all mush file
metacharacters before invoking the shell.  That would solve the problem
zfolder encounters.
