[PATCH 0/6] realpath cleanups

[Eric Blake]

As promised, here's my cleaned up series for http://debbug.gnu.org/10472

I'm not sure whether to squash 2 and 3 into one patch.

I'm not sure whether we want patch 6/6, so I documented the current
behavior in 5/6; if we want both, then it's best to squash the two
together (that is, effectively get rid of 5/6).

I've tested this on both Linux and Cygwin, to ensure that things behave
regardless of whether // is special or just an alias for /.

Eric Blake (6):
  test: expose recent gnulib canonicalize bug
  realpath: fix problems with root handling
  tests: cover more realpath scenarios
  realpath: let --relative-to default to --relative-base
  doc: clarify current realpath --relative-base behavior
  realpath: let --relative-base work even as child of --relative-to
