>Description:
	vgrind -f breaks on input files including C-like \-sequences,
	replacing the characters following the \ with something wrong.

>How-To-Repeat:

	miyu% cat h.c
	#include <stdio.h>
	
	int main(void)
	{
	        printf("hello world!\n");
	
	        return 0;
	}
	miyu% vgrind -f < h.c | nroff | head 
	#include <stdio.h>
	
	int main(void)
	{
	     printf("hello world!0);	<--- note the broken strings here!!!
	
	     return 0;
	}


>Fix:
	The problem lies somewhere in /usr/libexec/vfontedpr, and shows
	only if it's called with the -f flag (which is passed if -f is
	given to vgrind). If vfontedpr is called directly without the -f
	flag, this works ok. No other flags were tested, though, and the
	only input language around here right now is C. YMMV.

	Anyways, I leave this to someone with more clue on *roff.
