• VSCode Version: 1.14.1
• OS Version: All

Steps to Reproduce:

1. Enable quickSuggestions and wordBasedSuggestions.
2. Type some C++ code like "#pragma o".

Bug: The "o" on Enter will get autocompleted undesirably and there's no way for the language extension to disable the wordBasedSuggestion. VS Code has the comments and strings settings, but it doesn't allow extensions to have it's own classification to disable quickSuggestions (i.e. if the extension knows the code is like a comment/etc. and shouldn't autocomplete).

Reproduces without extensions: No
