The regex has to match the entire line because that is what it says it
does: append if no line matching.
I do think that cfengine is somewhat inconsistent in the implementation;
some of the editfiles functions have a 'contains' variant that does a
substring match, some only match the full line, and some have a 'starting
with' substring match. For consistency I think that either they should
all just do line matching (using rexexp to enable substring matches), or
all have a *LineContaining variant.
