Kakoune v2021.11.08-135-geae8ea8a

Reproducer

Output of ! command executed after i<a-semicolon> triggers completion which if completed by <c-n> produces wrong result.

Reproducer 1:

kak -n -e 'exec \% c canonicalize<esc>o<a-semicolon>!printf\ canonicaliz<ret> <c-n>'

Reproducer 2:

kak -n -e 'exec \% c canonicalize<esc>o<a-semicolon>!printf\ canonicalize<ret> <c-n>'

Outcome

Output 1:

canonicalize
canonicalizez

Output 2:

canonicalize
canonicalizee

Expectations

Correct completions.

Additional information

Not sure but maybe it is because of #1468.
