[PATCH 0/4] {minor} Modernize the install-sh script

These patches are intended for the 'micro' branch, so that they
will appear in Automake 1.15, but not in the future releases of
the 1.14.x series.

I intend to push these tomorrow or the day after.

Stefano Lattarini (4):
  install-sh: assume 'dirname' is available and working correctly
  install-sh: assume ${var:-value} works as expected
  install-sh: assume that "set -f" and "set +f" work...
  cosmetics: untabify the install-sh script
