I didn't see this anywhere, so excuse me if it's already addressed...
I'm using TiddlyWiki 2.0.10, and I noticed that if I enter an html link
that contains a structure like http:\\
domain.com\SomeWord\index.html,
that "SomeWord" appears in the list of orphaned Tiddlers. Since it's
part of the actual link url, I can't just use the standard escape
characters to un-tiddle it.
