There was already this discussion:

    http://thread.gmane.org/gmane.comp.version-control.git/132560/focus=132561

which basically dismissed effort along this line with "If the perl
in your PATH is so broken that it can't be used for simple helpers,
then you should fix your PATH."

I personally do not mind if we do this consistently, but I am not
sure your $PERL_PATH that is not quoted is the right way to invoke
it; look for PERL_PATH in t/ to see the existing uses.
