>Environment:

	I don't run FreeBSD-current, but this patch is against
	current-src/src/contrib/libreadline/display.c (built in
	current-src/src/gnu/lib/libreadline).

>Description:

	Problem with readline line wrap when the prompt is longer than
	the screen width and contains invisible characters.

>How-To-Repeat:

>Fix:
	
	Here's the patch:

*** ../readline-2.2/display.c	Mon Aug  4 15:54:23 1997
--- display.c	Fri Apr 24 14:23:35 1998
***************
*** 424,428 ****
--- 424,435 ----
    while (lpos >= screenwidth)
      {
+ #if 0
        temp = ((newlines + 1) * screenwidth) - ((newlines == 0) ? wrap_offset : 0);
+ #else
+       /* XXX - possible fix from Darin Johnson <darin@acuson.com> for prompt
+ 	 string with invisible characters that is longer than the screen
+ 	 width. */
+       temp = ((newlines + 1) * screenwidth) + ((newlines == 0) ? wrap_offset : 0);
+ #endif
        inv_lbreaks[++newlines] = temp;
        lpos -= screenwidth;
