No. you still use a regular expression, but without "\\(..\\)" surrounding
it (this was used for subexpression replacement. i.e.
you have str="hello world...", then you do
(string-match "\\(hello\\) world.*" str)
which gives you
(match-string 1) => "hello"
and you can easily replace the subexpression with "").
If you still do this, it will confuse Gnus because your regular-expression
is wrapped in another one, which uses \\(..\\) to find subexpressions..

C-h v gnus-list-identifiers:

gnus-list-identifiers's value is 
nil

Documentation:
Regexp that matches list identifiers to be removed from subject.
This can also be a list of regexps.

You can customize this variable.

Defined in `gnus-sum'.
