Hi,

Recently I followed a tutorial on learning.gem5.org and used hg to clone
the gem5 source code. And I followed
http://learning.gem5.org/book/part2/helloobject.html and use `hg qnew` to
create an hg queue, but I got the error:

** Unknown exception encountered with possibly-broken third-party extension
hgstyle
** which supports versions unknown of Mercurial.
** Please disable hgstyle and try your action again.
** If that fixes the bug please report it to the extension author.
** Python 2.7.13 (default, Jul  2 2017, 22:24:59) [GCC 7.1.1 20170621]
** Mercurial Distributed SCM (version 4.2.2)
** Extensions loaded: strip, mq, hgstyle

I had to disable the hgstyle extension in ${GEM5_SRC}/.hg/hgrc to make it
work.
