+1. You could probably ignore any lines where the first
non-whitespace char is '%'. But if that seems to risky, then only
recognizing first-char-is-% seems a worthwhile heuristic.
Another place where this has bitten people is when they do:
%\usepackage{Sweave}
Sweave picks that up and doesn't insert the usepackage line itself.
So ignoring LaTeX comment lines would solve two problems.
Best,
