I like the PS1.  Wasn't really fond of PS2.  I think I fixed
that...

      export PS2=":\r"

Now, the continuation prompt is ':', BUT the cursor is moved back
to the beginning of the line so the next thing you type overwrites
it, removing it from any future copy/paste.

This eliminates the every-other-line-is-a-comment thing.

note: if you have a blank line in your pasting, you end up with
a : in your next copy/paste, which works a bit like a comment in
bash and ksh. But it might be unexpected.  A '#' would work, but
that was too much like a usual shell prompt for my tastes.
