bisect-runner.pl needs to know how to identify HP-UX's patch.

Unlike AIX, HP-UX patch offers no meaningful clue as to its upstream version:

$ patch -v
$Header: patch.c,v 76.1.1.2.1.3 2001/12/03 12:24:52 abhinav Exp $
Patch level: 0

But it ignores unified diffs, so assume the worst and feed it context diffs.
