New Revision: 286971
URL: https://svnweb.freebsd.org/changeset/base/286971

Log:
  sh: Add test for $'\u' without any digits.
  
  It is likely that $'\uXXXX' and $'\UXXXXXXXX' will allow fewer digits in
  future. However, no digits at all should still be disallowed.

Added:
  head/bin/sh/tests/parser/dollar-quote12.0   (contents, props changed)
Modified:
  head/bin/sh/tests/parser/Makefile
