Er, that's the same one I mentioned in my note :-)

The advantage of updating scripts/completion.pl is that it's a
completion script generator.  Once it learns about bash syntax, new
options are added automagically if its run during the curl build.   Only
new syntaxes would require updating the generator. And, of course, more
shells can be added if there's demand/energy.

The one we found on github would have to be updated every time you add
or change an option - which isn't rare...  Think of it as something that
could have been produced by scripts/completion.pl (but probably was
hand-crafted).  curl could pull it in, but unless you set up a
relationship with that project, it's likely to always lag curl
releases.  Conversely, if curl builds generate a satisfactory script,
curl could push to that repo in addition to distributing it yourself.
