Lightweight detection of VCSCommandVCSType

[GoogleCodeExporter]

While there is "VCSCommandEnableBufferSetup", I just want to setup 
b:VCSCommandVCSType (for use with 
git://github.com/tomtom/quickfixsigns_vim.git).

Therefore I am using the following in my vimrc currently, but think that it 
would be better to provide this functionality out of the box:

    au BufRead * try | call VCSCommandGetVCSType(bufnr('%')) | catch /No suitable plugin/ | endtry 

Maybe something like a new command "VCSCommandSetupVCSType" so that I could use 
something like:

    au BufRead * VCSCommandSetupVCSType

Why do you need to detect the type before using a vcscommand command on the 
buffer?

This is used by https://github.com/tomtom/quickfixsigns_vim to add annotations, 
like only if the vcs type is defined for a buffer, it will pull and add the 
additional information.

See 
https://github.com/tomtom/quickfixsigns_vim/blob/master/autoload/quickfixsigns/v
csdiff.vim for the handling of this.

It looks to me like vcscommand itself cannot provide all the information 
required by quickfixsigns, or could it?
Then it would make more sense to make use of vcscommand completely from 
quickfixsigns.
