[Groff] groescp update

[Roger Leigh]

An update on the groescp driver:

I should receive the copyright assignment paperwork this week, so I
should be able to send you a working version of the driver soon.
There's just a few more things I need to sort out:


grotty (or just -mandoc?) disables headers and footers except for the
first header and last footer.  I need to re-enable them, if possible.

I was using the extended character set of the printer, but this isn't
portable across printer models: I'll need to use tty-char.tmac to
provide them, and only use plain ASCII :-( I can't even rely on the
standard codepages 437 and 850, since these aren't supported on every
printer (and ISO Latin 1 is very rare).  An escp.tmac which includes
tty-char.tmac should sort this out.

The manpage needs doing.


Other than that, there's very little left to do, since it's quite a
simple driver.


Regards,
Roger
