The `FNORD hack' isn't that uncommon, though I'd pick a better string,
one that's a lot more random. FNORD43dfg246432sdg ought to do :)

Personally, I only use sed for command line stuff. If it's
complicated enough to put into a file, it's perl and never awk or sed.
Now, /bin/sh vs. perl, that's not so easy. Quite often I start out in
/bin/sh and wish I'd started with perl later :)

Good habits :)

You don't need the `go' there at all.

s/%.*// ; would be more efficient.

g Match globally, i.e., find all occurrences.
o Compile pattern only once.
Read perldoc perlre, perlrequick and perlretut while you're at it.
/o is a performance thing. You rarely need it.

It's a hack, but it's not a really bad hack, as long as you pick a
good string. FNORD isn't good enough -- it's a real word, sort of.
But how about this --
s/([^\\])%.*$/$1/ ;
s/^%.*$/ ;
That ought to do it. Not that I know Latex, so I'm assuming that what
you've said is correct about parsing it.
