RFR(xxs): 8227170: (.hg)Ignore the JTwork and JTreport directories generated at the root of the repo

[dean.long at oracle.com]

The ** syntax isn't working for me in Mercurial 2.9, but the following:

syntax: glob
JTreport/*
JTwork/*

seems to work in both 2.9 and 4.6.1.  This also seems to work:

syntax: glob
JTreport
JTwork

but it matches files and not just directories.
