[Bug preprocessor/24024] [3.4/4.0/4.1 Regression] gcc -E -C processes "\" incorrectly inside C comments

Looks like the issue is that lex.c:save_comment() doesn't look at line_note's.
An analogous issue happens with trigraphs.

Btw, the C standard _does_ require escaped newlines and trigrpahs to be
processed in comments.
