Oddly, I feel happier running bash on Gnome-terminal than an emacs
shell process.  What GUI window Perhaps I'm spoilt by some of the
features like colour.  Maybe I'd be happier if I could work how to
get bash's emacs mode to work when running under emacs.  I'd be grepping
such material rather than viewing it. Moreover, I may be looking
through a lot of files rather than viewing a single one.

I don't need fixed-width cells.  But otherwise, there are uses for both
terminal emulators and teletype emulators.

Different scripts (and languages within a script for that matter) merit
different cell aspect ratios.

So, what do you recommend I run grep from for Hebrew or Tai Lue?
