I haven't tested, but it looks like it won't work with remote processes
foo and bar. Something like
--8<---------------cut here---------------start------------->8---
~ $ cd /ssh:remotehost:
/ssh:remotehost:~ $ *ls | *grep a
--8<---------------cut here---------------end--------------->8---
I have no idea whether such a usage pattern makes sense, but it seems to
work ATM. The alternative, calling "*ls *| *grep a", works as well, but
there are different results.
Best regards, Michael.
