 * $Log: util.h,v $
 * Revision 1.3  1997/02/13 21:10:45  jmg
 * Fix a problem with patch in that is will always default, even when the
 * controlling terminal is closed.  Now the function ask() will return 1 when th
 * input is known to come from a file or terminal, or it will return 0 when ther
 * was a read error.
 *
 * Modified the question "Skip patch?" so that on an error from ask it will skip
 * the patch instead of looping.
 *
 * Closes PR#777
 *
 * 2.2 candidate
 *
 * Revision 1.2  1995/05/30 05:02:38  rgrimes
 * Remove trailing whitespace.
 *
 * Revision 1.1.1.1  1993/06/19  14:21:52  paul
 * b-maked patch-2.10
 *
 * Revision 2.0  86/09/17  15:40:06  lwall
 * Baseline for netwide release.
