Tag matching regex is too aggressive, should not ignore whitespace

[lonix1]

These comments are shown in red:

//! foo bar baz
// ! foo bar baz

But sometimes you don't want that:

// algorithm to determine foo
//   iserror: remember to do bar
//   !iserror: skip baz               <------ shown in red, incorrectly

The regex probably has this: \/\/\w*!. So it ignores the whitespace between // and !.

It would be helpful to be able to enforce only two types: //! foo and // ! foo. (Using a new backwards-compatible option, of course.)

Good idea. I think I'm somewhat reluctant to change behaviour these days, but I could maybe see something this working OK:

// ! this is coloured
//! this is coloured
// !this is not coloured

I would guess that last one is not a common use-case, and if I limit that one, it'll solve your issue also. Thoughts?

Probably good enough. That extra whitespace causes the issue, so ignoring would help. Hiding this behind an option would make everyone happy.
