If the error message only triggered a shelltest warning instead of a failure, then they're harmless, so we might as well silence them when running 'redo test' (which runs t/shelltest.do, which enables SHELLTEST_QUIET). We still want to print them when actually testing out shelltest.od, though, to help with debugging the script.

#
|
|
# Note that this file isn't really a test for POSIX compliance. It's a test
|
|
# for usefulness-compliance, that is, interpreting POSIX in a particular way
|
|
# for consistency, so that users of redo can depend on all the following
|
|
# functionality.
|
|
#
|
|
# Where POSIX makes a clear statement about something working a particular
|
|
# way, POSIX wins. But where POSIX is unclear on a point, I don't mind
|
|
# picking a particular way and requiring it here, if that makes writing
|

# scripts easier for everyone in the future.
