pic lint

[Doug Gwyn <gwyn>]

Upon looking into the "pic" bugs reported by William LeFebvre
in UNIX-WIZARDS, I found that the DWB 1.0 version of "pic"
already has most of the parameter type problems fixed.
However, one bug remained and is fixed as follows:


picy.y line 15:

%token	<p>	TROFF	9		/* was <i> */


troffgen.c lines 6, 10, & 12:

	char *s;			/* was YYSTYPE */

	if (strncmp(s, ".PS", 3) == 0)	/* was s.p */

	savetext(CENTER, s);		/* was s.p */
