asm/preproc.c: remove dead code, improve comment

Browse source 
ppscan() had a break; statement followed immediately by a return
statement. The latter was left over from code restructuring and is
dead code.

Remove it.

Fix a nearby comment indicating that we should not need to strip a
const from a string pointer. Probably Token::t_charptr should be
const, but it might need additional work.
