Ooops! It's wrong. It should be
^subject:\s*(\(no[_ ]subject\))?\s*$
The original wouldn't match anything.
It says:
^ - the start of the line
subject:
\s* - zero or more white space characters
( - beginning of a group (this is why your original try didn't work)
\( - a literal (
no
[_ ] - a single underscore or space (character class)
subject
\) - a literal )
) - end of the group
? - zero or one occurrences of the preceding re, in this case what's
in the parentheses
\s* - zero or more white space characters (doesn't match \n)
$ - the end of the line
