Slow when syntax is off #16

Closed denten closed 9 years ago

denten commented 9 years ago

The plugin adds more than 2000ms to start up when syntax if off. This, I believe, is due to the lineisfenced() function that uses an `hassurroundingmarks()' that has slow regex parsing (well, slower than the syntax highlighter).

This is by design.

I'm being opinionated in my assumption that people who enable folding will already have syntax highlighting enabled. If syntax highlighting is disabled, I provide a fallback folding function which does the job but with poor performance.
