Subject: [patch] New testcase: py-prettyprint.exp: print hint_error

Hi,

PASS: gdb.python/py-prettyprint.exp: print hint_error
for
	FYI: fix buglet in gdbpy_get_display_hint
	http://sourceware.org/ml/gdb-patches/2010-07/msg00190.html
	http://sourceware.org/ml/gdb-cvs/2010-07/msg00061.html

I would check it in as obvious but the 2011 ChangeLog move process has to be
done first.  So to be checked in later.


Thanks,
Jan
