MacVim treats pauses in dictation as improperly-formatted new sentences without spacing.

As described in [this answer on Apple Stack Exchange, MacVim 7.4-77 (and other builds) do not seem to properly handle pauses in OS X dictation. This isn't a Vim issue, as Vim 7.4.889 on the same machine Does The Right Thing™.

For example, with MacVim:

I pause hereAnd dictation doesn't add a space.

but Vim itself works fine:

I pause here and dictation does add a space.

It's unclear why MacVim and Vim behave so differently in this regard. Expected behavior would be for MacVim to handle pauses in dictation without creating an improperly-formatted new sentence.

issue ではソースファイルもテストも特定されていません。まず MacVim で一時停止をディクテーションして動作を再現し、同じ macOS システム上の Vim と比較してください。MacVim が一時停止の後に期待どおりスペースを挿入すれば完了です。
