           pkgsrc/mk/checksum: checksum

   Log Message:
   Speed up the algorithm to determine the files left to check.

   This change modifies the algorithm used to keep track of the files that
   have not yet been checksummed to use a simple loop instead of shell pattern

   For packages with few distinfo entries, either way yields the same result
   as the list of files to check is very short.  But for those packages with
   hundreds of distinfo entries (vim, I'm looking at you), the difference is
   huge.  In my old macppc machine, the checksum of vim used to take around
   40 minutes and now it takes ~35 seconds.  The difference is also clearly
   visible in my faster amd64 machine (although I haven't bothered to time it).
