Comment 22 for bug 130687

I still wonder if "eq_case_blanks" is really better name for operator. there are another idea when I thought of. it is to make the case-sensitivity and ignoring blanks optional.

  <test name="family" compare="eq" case-sensitivity="false" ignore-blanks="true">
    ...
  </test>

the concern is, it's only effective for string. but that may be ok since fontconfig implicitly adjusts the behavior against the operator in even current implementation. e.g. FcOpContains and FcOpListing is equal to FcOpEqual for integer and float.
