From e1e948c76eb5817bac9e6e4dbbc30fe62e010f62 Mon Sep 17 00:00:00 2001

Subject: Rewrite the expression parser for a more concise syntax:

 apropos [search_type[,...]=]substring
 apropos search_type[,...][,i]~regex

... and expression evaluation must take the search type into account.

This allows to:
* drop the global -I option and
* drop the enum match, just using a boolean int.
