Add more options

[eight04]

Currently (~7.3.1), Linkify Plus Plus is so greedy that you can only stop it by adding specified elements to ignore filter. Should we let users adjust more detail behavior?

Current:

• Protocol is not checked. Any word can be a protocol if it suffixes with ://.
• Domain must have a valid TLD.
• The slash can be skipped if there are only domain followed by query string. (http://stackoverflow.com/questions/1617058/ok-to-skip-slash-before-query-string)
• Four numbers IP address will always be linkified.
• Consider underscore as a separate character.

Strict mode? (not implement yet)

• The link must be surrounded by spaces.
• If it is not surrounded by spaces, it must be surround by separate characters (e.g. brackets) that surround by spaces.
• Force lower-case domain.
• Limit the length between each period in the domain.

surrounded by spaces and fuzzyip options are added in 7.4.0.

The option works great but I still wonder why the underscores are considered as separators by default? Do people often type things like _www.site/foo_ ?

[eight04]

I don't remember. Probably some sites use it as a separator? (e.g. markdown?)

An interesting thing is that trailing underscores are not removed so _www.site/foo_ becomes _[www.site/foo_].
