  Modified files:
    contrib/cvs/src      recurse.c 
  Log:
  Fix a serious bug in the recursion processor.  When descending a tree,
  the descend can jump several directories down in one hit, eg: when a user
  mentions multiple directories on the command line, eg: "cvs diff
  sys/i386/isa/snd sys/sys".  The problem is that the chdir()s are
  pushed/popped to account for this, but the "full path" merely has
  the last component chopped off on the way back up.  This busts lots
  of things when the recursion is backing up more than one directory (such
  as in the example).  This causes 'cvs diff' to emit bogus Index: lines,
  'cvs update' to do really stupid things, 'cvs commit' to record incorrect
  pathnames etc.  I'm not sure that what I've done is quite correct, there
  seems to be a comment that implies some sort of problem with "." vs. ""
  equivalence or not, perhaps this is a problem on some other OS's, but
  I've not (yet) found any problems.  This bug has been present since
  at least cvs-1.8.1.
  
  This should fix problems noted by several people including asami and jmg.
