[PATCH 0/3] mixed bag of -Wunused-parameter bugfixes

Here are three minor bug-fixes that can be applied independently. The common thread is that I found them by looking at the results of compiling with -Wunused-parameter. In each of these cases, the parameter _should_ be used, and not doing so was a bug.

  [1/3]: rev-list: handle flags for --indexed-objects
  [2/3]: approxidate: handle pending number for "specials"
  [3/3]: pathspec: handle non-terminated strings with :(attr)
