Avoid restarting completion after picking a word (#246)
Avoid restarting completion after picking a word (#246)

Fixes #244

We get another `TextChangedI` after hitting "enter" to choose a
completion. Since `s:next_char` was still set to whatever character was
typed last during the completion, we think we need to complete again.
Emptying out `s:next_char` avoids this.
