according to SUSv3 and other modern shells (POSIX allows both). Idea for the patch (add another lex state) from OpenBSD, but the implementation differs slightly (and is better in quality). Also add two testcases (/bin/sh passes both, old mksh only one), and document the change in the manual page. Sync RCS IDs with OBSD.
