/* ---------- "patch 2.0 patch #1" ---------- */
System: patch version 2.0
Patch #: 1
Priority: MEDIUM
Subject: Backwards scan for place to insert hunk can give up prematurely
From: dorab@ucla-cs.uucp (Dorab Patel)
Description:
Under certain circumstances patch can fail to find the correct
location to install a hunk. If the proper place to insert a hunk
is more lines backwards than the number of lines left in the input
file from the place it first starts searching from, patch gives up
because of a more-or-less typographical error.
Fix: From rn, say "| patch -d DIR", where DIR is your patch source
directory. Outside of rn, say "cd DIR; patch <thisarticle".
If you don't have the patch program, apply the following by hand,
or get patch.
If patch indicates that patchlevel is the wrong version, you may need
to apply one or more previous patches, or the patch may already
have been applied. See the patchlevel.h file to find out what has or
has not been applied. In any event, don't continue with the patch.
