Subject: Special character (like TAB) in rules

Solar, thanks for your efforts.

Is there a way to specify specific non-printables in rules? Say I want 
to prepend a TAB, or match a TAB and replace with a BEL, just as 
examples. The documentation does not mention any way to do this. In 
external modes, I can use 0x09 of course.

A generic way to specify *any* non-printable, like \x09 or something to 
that effect, would be very usable. I thought of placing this 
functionality in the preprocessor but keep in mind you may want to use 
it in a PP list (like [0-9\x09] for digits + TAB) too. Or even a CR or 
LF for that matter. I haven't looked into it yet, any comments off the 
top of your head?
