RedCloth produces double content for extended block with unrecognized tags
Reported by Georg Friedrich | March 25th, 2011 @ 04:37 AM
RedCloth 4.2.7 doubles the content for extended blocks for unrecognized tags.
Here is an example:
#> RedCloth.new("foo.. bar\n\n").to_html
=> "<p>foo.. bar</p>\n<p>foo.. bar</p>"
The problem is that in red_block() the call
CLEAR_REGS() doesn't clear the fallback key out of the
register but assigns a new hash to the local variable.
I added a test case and fixed the problem here https://github.com/georg/redcloth/commit/d66e83bca2bf0457a703272b2f...
I can submit a pull request if you think the fix is okay.
