What do you think of this solution:
The intention is for the 1.0 script to be renamed to
gstreamer-completion-1.0 with the two entry functions renamed to
_gst_inspect_1_0 and _gst_launch_1_0, but for all the remaining helper
functions to be shared between the 1.0 and 0.10 completion scripts
(because neither the format of the gst-launch pipeline, nor of the
output of gst-inspect, have changed from 0.10 to 1.0).
