# Test whether CR #6754020 ("ksh93 does weird '[' expansion") has
# been fixed.
#
# Quote from CR #6754020:
# ---- snip ----
# The problem is that subprocess uses /bin/sh as the shell when it
# spins off the process. As Brad demonstrated:
# /bin/sh -c 'echo F[[O]'
# F[[O][
#
# In short, this bug only appears when run through the test suite,
# or by people  running /bin/sh who don't understand how their shell
# treats special characters.
# -- snip --
#
# In this case ksh93 has a bug which causes "F[[O]" to be expanded
# in a wrong way.
# ---- snip ----
