New Revision: 292758
URL: https://svnweb.freebsd.org/changeset/base/292758
Log:
sh: Add tests for #/##/%/%% on $* and $@.
Although POSIX leaves things like ${*#X} unspecified, it occasionally occurs
in practice. Add some tests that seem to work sensibly.
Added:
head/bin/sh/tests/expansion/trim9.0 (contents, props changed)
Modified:
head/bin/sh/tests/expansion/Makefile
