It does not. It seems that cfengine is not capable of back
referencing in the replacement text. Neither \1, $1, ${1}, $(1), or &

This is sad.

I agree. However, one of the beauties of cfengine is that the code is pretty readable. I suspect that by looking at the GlobalReplace function in item-ext.c, and the "regexec" man page, you'll be able to figure out how to fix the problem (GlobalReplace is called from edittools.c).
