lintian(1) (that's a Debian QA tool) expects a comma-separated list, and the
above completion fails.

Any idea how to accomplish this? The expected behaviour would be (| cursor, <>
tab):

$ lintian -T <>
tag1,   tag2,    tag3,
$ lintian -T tag1,<>            # The first one gets correctly completed
tag1,   tag2,    tag3,          # I don't really care whether it repeats "tag1"
$

While it currently does:

$ lintian -T <>
tag1,   tag2,    tag3,
$ lintian -T tag1,<>
$ lintian -T tag1,|

The same goes with some other options, which I didn't notice accepted a
comma-separated list (it doesn't matter whether there is a trailing comma, even
if it would be nice to drop it)

Any idea on how to achieve this?

Otherwise, I can offer completion just for the first item, then go back to
options completion.

Kindly,
David
