[PATCH] regex.3: wfix

[Alejandro Colomar]

The wording was incorrect:

It stated that 'eflags' may be the OR of one or two of those two flags,
but then a third flag was documented
(which according to the previous wording could not be used?!).
Moreover, the wording also disallowed using 0 (i.e., no flags at all),
which POSIX specifically allows;
I tested the function with no flags and it worked fine for me,
so I guess it was a problem with the documentation,
and not with the implementation itself.

Hi Michael,

I was working with the example, and the documentation was a bit weird,
so I want to be sure I'm doing it right before sending you the example.
Please review that this patch is correct, which I guess it is.

Cheers,

Alex
