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:
