Hello all; This change addresses a problem discovered by Dave Pointon.
http://cr.openjdk.java.net/~mduigou/JDK-8029512/0/webrev/ If the .hg/hgrc file contains (perfectly legal) spaces around the = sign of an assignment then the current script will fail to correctly read the path definition. This patch corrects the parsing of the hgrc file and also protects against empty results. I plan to commit this to the JDK 9 repo first but expect that it should be backported to JDK 8 and JDK 7 repos. Mike
