tests/lint: make 'expect+-' comments stricter

Previously, the expectations from these comments were already satisfied
if the expectation occurred somewhere in the actual message from lint.
This meant that the prefix 'error:' or 'warning:' could be omitted from
the 'expect' comment.  These omissions were hard to see in a manual
review.  Now any omissions must be visually marked with '...'.

The test msg_342 now reports its messages properly as being in the file
msg_342.c, rather than msg_341.c.  This had been a copy-and-paste
mistake.

lint: revert fix for endless loop in lexer for string literals

String literals may contain null bytes, and these must be passed further
on.

This reintroduces the endless loop in the lexer, but that must be fixed
in another way that doesn't destroy the error handling.
