Interwiki regexp bug

given an interwiki mapping configuration such as
"Local drupal path | local | /%s"
a wiki link such as:
* [[local:rapicorn/rdocu-rapicorn/index.html| API Reference]]
gets mis-parsed and yields:

note the "local%3A", respectively "local:" in the href.

this is due to a misplaced '-' in the interwiki regexp character
set. to include '-' in []-braketed regexp character sets, the
hyphen must be noted at either end of the character set:
