Delimiter escaping broken

[natevw]

Issue #146 added the ability to escape delimiters to pass on to e.g. client side templating engines, but as @reedlaw and @shtylman tried to point out in the comments, it's very broken. My guess is that it's only properly applying to every other tag in the input, but YMMV.

Input:
"{{var1}} in the {{var2}}"

Expected output:
"{{var1}} in the {{var2}}"

Actual output:
"{{var1}} in the "

I just tried this on a larger template that I was attempting to use to produce another template, just to see if the version I'm using has this problem. It does, and it appears to be an "every other" problem as the note above says.
