Regression: `<C-f>` is appended to `indentkeys`

[e-kwsm]

Warning: I will close the issue without the minimal init.vim and the reproduction instructions.

Problems summary

If I insert a word that ends with do—do, sudo, or todo—in a shell file, then <C-f> is appended.

This bisects to e54a5c674d9107c886c3cf8e39a9f6394645f9b8 (#105; the revisions of the other plugins shown below are pinned).

Expected

<C-f> is not appended.

Oh, the indentation is broken.

[e-kwsm]

<C-f> is appended to one of indentkeys: this also happens with elif and except in Python.

[Shougo]

Fixed. Please update ddc-ui-native.
