* 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.
