After :EnvimSymbolAtPoint or :EnvimUsesOfSymbolAtPoint syntax highlighting goes away

[megaannum]

Start vim and enter :Envim. After all is ready, read in a file to edit
(:e SomeScalaFile.scala).
Next place cursor on symbol and enter either
:EnvimSymbolAtPoint or :EnvimUsesOfSymbolAtPoint
and all syntax colors go away. The commands work, just the syntax colors
disappear.
The work around is to enter :e and syntax colors come back.

BTW, this occurred using the vim-scala-behaghel addon (it also occurred
with my normal scala.vim syntax plugin but I figure I ought to report it
using a reproducible set of scala vim syntax code).

This in part has to do with issue 10 where I would close the QuickFix window and
then Vim for some reason forgets the curent window's file type.

If the file envim/ftdetect/scala.vim has
au BufRead,BufNewFile,BufEnter *.scala set filetype=scala
then most of the time, syntax highlighting happens.
It does not happen if UsesOfSymbolAtPoint does not have a match, and thus
the scala buffer is never exited so that it can not be re-entered.
Somewhere in the UsesOfSymbolAtPoint (and SymbolAtPoint) code, the
filetype of the buffer holding the scala source is being removed.

Hey,

Right, I have already noticed such a behavior at some points.

However, on macosx the issue does not appear. Certainly some hidden secrets of our dear Linux :)

Thanks for the possible patch. I would like to look at it in depth since it does not completely fixed the issue.
