Subject: Bugfixes: Consistent escaping in various literals. Double backslash
 codes for single backslash. Output clause can be empty.

* parser.l (char_esc): Backslash handled.
Use internal_error rather than abort.
(REGCHAR, LITCHAR): Backslash added to lexical syntax.

* parser.y (output_clause): Allow empty output clause.
