freebsd/bin/sh/tests/expansion/plus-minus3.0
Julio Merino 13de33a5dc Migrate tools/regression/bin/ tests to the new layout.
This change is a proof of concept on how to easily integrate existing
tests from the tools/regression/ hierarchy into the /usr/tests/ test
suite and on how to adapt them to the new layout for src.

To achieve these goals, this change:

- Moves tests from tools/regression/bin/<tool>/ to bin/<tool>/tests/.
- Renames the previous regress.sh files to legacy_test.sh.
- Adds Makefiles to build and install the tests and all their supporting
  data files into /usr/tests/bin/.
- Plugs the legacy_test test programs into the test suite using the new
  TAP backend for Kyua (appearing in 0.8) so that the code of the test
  programs does not have to change.
- Registers the new directories in the BSD.test.dist mtree file.

# We follow original ash behaviour for quoted ${var+-=?} expansions:
# a double-quote in one switches back to unquoted state.
# This allows expanding a variable as a single word if it is set
# and substituting multiple words otherwise.
# It is also close to the Bourne and Korn shells.
# POSIX leaves this undefined, and various other shells treat
# such double-quotes as introducing a second level of quoting
# which does not do much except quoting close braces.
