FTM update

• 12:29 Trying to figure out a good API/structure for calculating the relative paths that need to be shown in the status.
  • FSLink->PathTo() does the actual work, but needs to be called from the base link (the start of the relative path); the problem is where to store the base link so we can get to it where needed.
  • "Where needed" is in [FTM] Mover->HandleFile(), which (currently) only knows the current Pair, not the base Pair or the base FSLinks.
  • The obvious solution, now that I write it out, is for Spider (which operates Mover) to call Mover when starting a tree and pass it either one of the base FLinks (by convention, we use the source-link when it doesn't matter which one but everyone has to agree which one is being used).
• 12:36 It turns out that Mover's base-class, Match, already has DoStart() and DoFinish methods, neither of which are called or implemented which for some reason are incompletely used (only DoFinish() was being called, and both methods are just stubbed off in the base) -- but this is exactly what they should be for. (Do I want to convert them to Events, though, maybe? For now, let's say "no"...)
• 12:45 ...except there are two design issues:
  • Can't do this outside the glob-loop because we need an actual filespec that will match something, and if we do it inside the glob-loop, then maybe we will need another start/finish pair for outside...
    • ...but given that nothing was using that pair anyway, maybe just ditch the whole idea of these methods for now and have one called something like BasePath.
  • We also don't have the FSNode yet. Maybe PathTo() will end up being irrelevant, since we can just do a string-excerpt? (...except then we can't do fancy formatting with the segments, later on...)
    • ...or maybe we should call it from inside DoTopFolder(), which is where the FSLink objects (and the Pair object, for that matter) are in fact created.
