+### Updated patch
 
->> Update:
+I've created an updated [patch](http://www.idletheme.org/code/patches/ikiwiki-format-escapes-rlk-2007-09-24.diff) against the current revision.  No real functionality changes, except for a small test script, one minor bugfix (put a "join" around a scalar-context "map" in convert_link), and some wrangling to get it merged properly; I thought it might be helpful for anyone else who wants to work on the code.
 
->> Thanks to the rst specification, I found that most of the glitches with
->> links can be solved. The remaining restrictions would be that wikilinks
->> expand with a trailing space (ie. pre\[[process]] works but \[[html]]ize
->> doesn't), and preprocessor directives which output HTML can only be used
->> as a standalone paragraph. I will update the patch tomorrow.
+(With that out of the way, I think I'm going to take a stab at Jeremie's plan to use marks which would be replaced post-htmlization.  I've also got an eye towards [[todo/multiple_output_formats]].)
