Consider the following example:

% _cmd () { _arguments -A '-*' : -a -b '*: :_file' }
% compdef _cmd cmd
cmd -x -<TAB>
No match for: `file'

But zshcompsys(1) says:

-A pat
  Do not complete options after the first non-option argument on the line.
  pat is a pattern matching all strings which are not to be taken as arguments.
  For example, to make _arguments stop completing options after the first
  normal argument, but ignoring all strings starting with a hyphen even if they
  are not described by one of the optspecs, the form is `-A "-*"'.

In the example above, -x should not be taken as a normal argument since it
matches the pattern '-*' (although it is not in the optspecs), and the
options -a and -b should still be offered here (if I understand the document

With the patch below, ca_inactive() is called only if
-A pat is given, and
the word under inspection ('-x' in the example above) does not
match the pat so it can be considered as a normal argument, and
the word ('-x') is before the cursor.
