- Note that the requirement is to allow the user to decide
- if the domain pattern should be interpreted as regex or
- traditional host pattern and if it's not obvious that the
- user made any decision, default to the latter.
-
- Possible solutions would be:
-
- 1. An always-use-regex-domain-patterns config option
- 2. An enable-regex-domain-patterns-for-this-action-file option
- 3. An enable-regex-domain-patterns-for-this-action-file-until-the-user-says-otherwise option
- 4. A treat-the-domain-pattern-in-this-line-as-regex(-or-not) option
- 5. Combinations of the options above
-
- With 2+4, 3+4 or 2+3+4 being the preferences until
- further discussion.
