# Usage: array_join join_on array

# Usage: expand <terminal-input> <flags> <stderr-file>
#
# Prints the string resulting from command expansion after the
# specified terminal input is typed at the shell. The argument
# is evaluated using 'echo -e', so \t can be used to invoke
# command expansion. STDERR output from the call to bash is
# sent to stderr-file so it can be inspected, if desired.
#
# This approach is rather gnarly, but guarantees good test fidelity,
# unlike "unit test" approaches based on invoking the completion function
# directly with COMP_WORDS etc defined.
