Vim plugin highlights single line comments nested within a multi line comment

[sfackler]

Something like this will highlight the //github.com/mozilla/rust part as if it were a single line comment.

/*
http://github.com/mozilla/rust
*/

You're right. This isn't noticeable by default, since rustCommentBlock is highlighted the same way as rustCommentLine with the default configuration.

Similarly the construct /*/**/*/ also mis-parses and considers the rest of the document commented out.

[lilyball]

Apparently /*/**/*/ is unsolvable in Vim's syntax mechanism, which is explained in a long comment, but boils down to the fact that Vim prioritizes a pattern start over a pattern end even if the end starts earlier than the start (this is an issue if they overlap).

[lilyball]

Well, to clarify, it's unsolvable if you try and solve /* */*. Somehow I have it in a state right now where /*/**/*/ actually works, although /* */* is still broken.

When I implemented comment nesting for Vim, I did it that way on purpose. It may have been misguided (I'm gently inclined to think it was, though still I think that differentiating nested comments is a convenient feature), but it was deliberate.
