Not terrible, but I've never seen syntax like that.

Yes -- that's explained in the INSTALL file. No options is equivalent to
all three options (a shortcut).

If there is a "most-accepted" way, it will no doubt involve syntax that
people might mistakenly type. The only other decent way to say it I can
think of other than the current, which is just:
--enable-masquerade[='draft_from mmailid username_extension']
enable 3 types of email address masquerading [none]
would be to say:
--enable-masquerade[='MASQUERADE_OPTION_1[ MASQUERADE_OPTION_2...]'
enable up to 3 types of address masquerading [none]
I had wanted to spell out the possibilities in the --help, though. I guess
I could add a third line to the --help output for that option, but... ;^>
