Yes, but elsewhere don't we need its name?  So I was thinking of a
function returning the name.  If it is non-null that would indicate the
presence of a wireless interface.

No.  This is incorrect because 'no wireless extensions' is output on
stderr, not stdout.

Yes, I thought of that, but it looked slightly more complicated to
parse out the wireless name.

Surely we are not the first to want to determine this.  Isn't there an
implementation of this anywhere else in Debian?  I started to look but
admit I didn't do a very careful or thorough search.
