( ported from Microsoft/vscode-editorconfig#24 )

Repro'd on editorconfig v0.2.7:

1. Enable autosave in VS Code (e.g. in user settings) - great for users who are used to using Git to back up their code.
2. Open up a workspace that lacks VS Code workspace settings for files.trimTrailingWhitespace.
3. In the same workspace, create a .editorconfig, setting trim_trailing_whitespace = true

Type some code with spaces, then rest (wait for autosave delay).

Expected: Caret position remains, trailing whitespace preceding the caret is not trimmed
Actual: All trailing whitespace is trimmed, causing the caret to move and the code (whitespace) that was under composition to be deleted.

Note, this caused me to stop using trim_trailing_whitespace for a while, before I realised that enabling the matching VS Code option overrode the behaviour to be correct. However, figured it was worth reporting so that this could be improved for new users.
