regex: read/print bug: escaped double quote.

Because the regex printer wrongly uses out_str_char (for the
sake of borrowing its semicolon-notation processing) when
a regex prints, all characters that require escaping in a
string literal get escaped, which includes the " character.
Unfortunately the \" sequence which results is rejected
by the regex parser.

* lib.c (out_str_char): Kludge: add extra argument to
distinguish regex use versus string use, and treat the double
quote accordingly.
(out_str_readable): Give 0 arg to new param of out_str_char.

* lib.h (out_str_char): Declaration updated.

* regex.c (print_class_char, print_rec): Pass 1 to new param
of out_str_char.
