Bash 3's completion doesn't split words by characters in
COMP_WORDBREAKS. In particular it doesn't split at "=" signs. Now
_gst_launch_parse handles both bash 3 and 4 format of COMP_WORDS.
Note that "${cur%%=*}" means cur's value with the longest possible match
of "=*" deleted from the end; "${cur#*=}" means cur's value with the
shortest possible match of "*=" deleted from the beginning. See
http://www.gnu.org/software/bash/manual/html_node/Shell-Parameter-Expansion.html
Regardless of the version of bash running the unit tests, I can test for
both behaviours because the unit test populates COMP_WORDS manually. So
this tests the bash 3 behaviour:
test_gst_inspect_completion --gst-debug-level=4
and this tests the bash 4 behaviour:
test_gst_inspect_completion --gst-debug-level = 4
