Thanks for the reply Chet, The completer is being setup in Bash, not directly through readline (sorry if I wasn't detailed enough in my original post). Even though readline might break the completion on the ':', we can use COMP_LINE/COMP_POINT to figure out the URL that needs to be completed (ignoring the ':'). The problem of course is inserting the results. No matter what we return from the completer, readline is going to insert it after the ':' which means we have to strip off everything up to ':' in the completion results. If the completer had a way to tell readline (through Bash) where the completion should be inserted that would allow a workaround for this issue without requiring any actions from the user. (This is probably not the most ideal solution, but I can't think of any other that wouldn't require major changes.)
