[Groff] delimiters for escapes

[Werner LEMBERG]

Dear friends,


I've just added some info to groff.texinfo which characters are
alllowed to delimit escape sequences.  The results are *very*
surprising...

Please look at it (type `makeinfo groff.texinfo' to produce info files
or type `texi2dvi groff.texinfo' to produce a DVI version).

Again, I'm interested in a comparison to UNIX troff...
