Specific to spamassassin, are capture groups ever useful, or should I
always use non-capture groups?
Eg. (lit) vs. (?:lit)
The only place I've found backreferences useful is when writing a header
rule that is looking for the same string in multiple headers.
Other than that, captures are very rare.
If SA had a way to capture a match from rule1 and use that in rule2 you
might see more of that.
