Fair enough - never used GNU that much, so don't know what it can do.
I'm not sure I'd be allowed to give you specific functions. You can,
however, freq "SNIPPETS.ZIP" from me which'll give you everything.
(It's /all/ useful, anyway)
Uhuh - can't remember now - you may well be right. Did it have
contingencies if it did reach eof?
Nooo! That's TmNice's tagline precursor - best use a more normal kind
of tearline "~~~ ","--  " etc. (Not "--- " as some software can't handle
two full tearlines). Unless, of course, you /wanted/ to have your tearline
stolen by every tagtool...? ')
That's the best idea. You could also check out rmtrail() in Snippets :) -
that removes ALL whitespace at the end of a string - including spaces,
tabs and CR/LF combinations. Then you know that it's tidy and you can
include a \n when you output it.
Not exactly difficult to best Termails. :)
No worries. I've done about as much as you can with taglines and
often wished I had someone who'd been there before to ask. ')
