Two gripes I have are:
(1) That sounds like making common things more cumbersome to ask.
(2) In "-L /RE1/,/RE2/", you do not have to say +/RE2/ (and you
shouldn't have to). /RE3/ without any magic that starts
searching after the last match in "-L /RE1/,/RE2/ -L /RE3/,+4"
feels a lot more consistent than requiring a prefix plus.
I am OK if you made /RE/, which starts searching immediately after
the last match, wrap around and continue the search at the beginning
upon finding nothing through the end of the file (and make sure you
stop if you passed the last match again). That would solve your "I
have two functions, and I can give them in any order", while keeping
the consistency with "In /RE1/,/RE2/, the latter is already relative
to the former".
