indeed, it's a bug. It should be fixable, I'll have a look. Thanks for the
Note that pysh only gets relatively lightweight use from me (for no particular
reason I don't use it fulltime, just habit I guess). Which means there are
probably lots of small things which don't work quite right. I'm thinking of
adding a pyshdebug magic toggle which would activate printing of the
auto-modified pysh lines, to ease with debugging.
ps. Thanks for helping John Lee with the emacs issues! I wrote yesterday to
you, but it seems the Colorado.EDU SMTP server has been blacklisted by
spamhaus, so my messages to sourceforge.net from the office now bounce. I am
now writing from home.
