I'm on trunk, but will commit and look at 1.1 too

ok, so ACRONYMS work this way - they are possible links for which the plugin can ammend the linktext.

remaining things to investigate:

1. why are the %'s removed from the web and topic values - making it impossible for the plugin to know if its a var or literal text
2. is there a problem with the ATTACHURL case (i suspect not putting http://foswiki.org/pub/Tasks/Item11526/releases/other/file-3.0.4.tar.gz causes foswiki to expect that there is a topic by that name.

ok, so fundamentally, I always forget that renderText must have all MACROS already expanded - it does not do it for you.

wrt ACRONYMS, Foswiki::Func::internalLink will return non-linked text, so taht can be used to detect that what is passed to the renderWikiWordHandler is not actually a link.

so, I've added a few more tests, and might have added just enough docco to help me in 4 years time when i hit it again.

merged over to 1.1 too, as its docco and tests.
