Bug#845778: vim: Speed regression in compl-dictionary when running without GUI.

[Torkel Bjørnson-Langen]

Package: vim
Version: 2:8.0.0095-1
Severity: normal

Dear Maintainer,

After upgrading vim from 2:8.0.0049-1 to 2:8.0.0095-1, dictionary
completion (ctrl-x ctrl-k in insert mode) got way slower (1-3
seconds); it used to be instantaneous.

This only happens in non-GUI mode. E.g., the regression does not
happen when running `vim -g`.

If I downgrade to the previous version (2:8.0.0049-1), the problem
disappears.

I did the testing with `dictionary` is set to
`/usr/share/dict/american-english`. And I followed the instructions
given by `reportbug`.

Best regards,
Torkel Bjørnson-Langen
