Texinfo reference cards

[Karl Berry]

I've finally incorporated the Texinfo reference card originally created
by Bob Solimeno (bcc'd, not sure he wants his email address so easily
harvestable ...) in the distribution.  Thanks Bob!

Letter-size PDF:
http://cvs.savannah.gnu.org/viewvc/*checkout*/texinfo/doc/refcard/txirefcard.pdf?root=texinfo

A4 PDF:
http://cvs.savannah.gnu.org/viewvc/*checkout*/texinfo/doc/refcard/txirefcard-a4.pdf?root=texinfo

The "cards" are actually four pages long (three columns, landscape).  I
haven't tried to actually print them or fold them.

Comments welcome.  I plan to release 4.13 in a day or two.
