I wrote a whole thing about how this wouldn't work, because
Lua bytecode already doesn't include whitespace and
comments, then I realized that of course you meant lstrip
instead of, not in addition to, bytecode compilation.
A bit of quick-and-dirty experimentation (very small sample
size) suggests that lstrip crunches very small files much
better than luac -s, but does only slightly better with
medium to large files.
