IPFW manpage suggestion

I have a friend who's converting from linux to FreeBSD. He's trying
to set up ipfw and was reading through the ipfw manpage. He asked me
some questions about examples in the manpage and while I think the
manpage is very clear it is perhaps a poor example.
As an example, an address specified as 1.2.3.4/24{128,35-55,89}
will match the following IP addresses:
1.2.3.128, 1.2.3.35 to 1.2.3.55, 1.2.3.89
This is perfectly clear and works exactly as stated but the choice of
1.2.3.4/24 as a network number isn't the best in my opinion. His
question was whether the example would match 1.2.3.4. It doesn't of
course but perhaps the example would make more sense as:
1.2.3.0/24{128,35-55,89}
This also opens to door to what happens if you do something like:
1.2.3.15/25{215-220} I regret to say I don't have a box I can
actually test that on though.
There are other places in the manpage where a network number would
make more sense than an IP but the one I pointed out seems to be the
most glaring.
I'm willing to do the grunt work if it's determined it's worth
changing.
