generated client spec contains backslashes leading die problems on unix os

When a client is created it is named:

E.g. sannies-sojus-MavenSCM-\opt\continuum-1.1-beta-3-SNAPSHOT\apps\continuum\webapp\WEB-INF\working-directory\6

that is ok, but now comes the sync command and uses following commandline

/bin/bash c "p4 -d /opt/continuum-1.1-beta-3-SNAPSHOT/apps/continuum/webapp/WEB-INF/working-directory/1 -cbackground-sojus-MavenSCM\opt\continuum-1.1-beta-3-SNAPSHOT\apps\continuum\webapp\WEB-INF\working-directory\1 sync"

The Bash now removes the backslashes in the client name! The result is that the client is not existent and perforce returns with an error.
This is related to [PLXUTILS-44] and CONTINUUM-1402

I propose to use the underscore character instead of the backslash.
