Subject: [PATCH] Portability fixes for popen.test (for when /bin/sh is not bash)

* test-suite/tests/popen.test (open-input-pipe no-duplicate): Pass
  "read REPLY" command instead of "read" to the subshell, for improved
  portability.  In particular, it is needed when /bin/sh is dash.

  (open-output-pipe no-duplicate): Pass "exec guile [...]" instead of
  "guile [...]" to the subshell, to ensure that the subshell will not
  run guile as a subprocess while holding a duplicate of STDIN, which
  would cause this test to fail.  This is needed when /bin/sh is dash.
