Problem with _configure argument autocomplete

[Andrew Ryan <nerdrew@xxxxxxxxx>]

The mod_wsgi configure script has the following options (taken from
./configure -h):

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-apxs=NAME        name of the apxs executable [apxs]
  --with-python=NAME      name of the python executable [python]


The "--with-python=NAME" option does not autocomplete the path
following the equal sign.

Adding the following to the end of _configure makes it autocomplete correctly:

'*=NAME*:directory:_files -/'

I don't know if this conflicts with anything else. I also don't know
how common "=NAME" is in configure script options.
