ArgumentOutOfRangeException in Winterdom.Viasfora.Text.BraceCache.FindIndexOfFirstBraceInSpan()

Getting this pretty often (version 1.2 installed):

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Thanks for the Bug report, Jon.

Has any specific repro scenario come up?

I've rewritten much of this code for v1.3, which should be out in a couple of days and so this specific error shouldn't happen anymore.

I've posted a beta version of 1.3 at http://winterdom.com/files/Winterdom.Viasfora.vsix you can try if you want.

Code completely rewritten in v1.3. As part of refactoring, the line cache was removed, eliminating the need to keep it in sync with the text buffer.
