Gidday from the upstream man-pages maintainer...
The upstream man page says:
Two colons mean an option takes an
optional arg; if there is text in the current argv-ele-
ment, it is returned in optarg, otherwise optarg is set
to zero.
This seems reasonably clear to me: "the *current* argv-element". So the
man page seems to me to clearly say that /-afoo/ will work, but /-a foo/
will not, because in the latter case "foo" is not in the "current" argv
element.
Nevertheless, I've added a few words to make the point crystal clear:
Two colons mean an option takes an
optional arg; if there is text in the current argv-ele-
ment (i.e., in the same word as the option name itself,
for example, "-oarg"), then it is returned in optarg,
otherwise optarg is set to zero.
Cheers,
Michael
