Completion Doesn't Work in New (Unsaved) Tabs

[aflatt]

I'm guessing this may be by design, but I've noticed that the completion system does not seem to work for any newly created tabs.

The follow procedure should illustrate the problem:

• Open an existing python file
• Type a word that would result in a completion (so far this works).

• Now I enter the vim commands

  :tabe
  :set ft=python
  
  * I enter some python code, in the newly created (unsaved) tab:
  
  ```python
  test = 1

• When I type the word "test", I'm not shown any completion menu, as I normally would see in an existing python file. When I do type, I see the following in the vim status bar:

  -- User defined completion (^U^N^P) Pattern not found

AFAIK, the file has to be saved and reloaded before the completion can do its magic.

This has been fixed on the ycmd brach of YCM. Don't use that branch, it's not ready yet. It should be merged into master in a week or so.

Thanks for reporting the bug and providing a good test case!
