Naah, I just used my spelling checker, which didn't have "lookahead".
I just now checked Google Scholar. It reports about 1,240 hits for
"parser look-ahead" (#1 is the Bison manual itself; #2 is DeRemer) and
1,450 for "parser lookahead" (#1 is Parr & Quong). (Maybe the LR guys
prefer a hyphen?:-)
Clearly either spelling is acceptable. It would make sense to
standardize on one. Personally I find myself in the (slight)
majority, and prefer "lookahead" without the hyphen, but I'm too lazy
to change everything myself.

Yes, but if 'p' is a simple variable normally it's easier to read this:
p = E;
if (p)
S;
than this:
if ((p = E))
S;
The situation is a bit different with 'while' loops, but for 'if' it's
no contest.

Yes. The original request was from Nicolas Joly of the Institut
Pasteur, who's using Bison-generated parsers to detect and parse
biological sequence formats. See
