Sure. So there will never be any way to get linear version numbers with 
git. The only way to understand if you have a revision is in your 
repository is to check with

$ git log <hash>

or

$ git log
and search for <hash>

If you do not have a repository, you need to guess based on the time of 
commit and checkout or you need to use a web interface to the repository.

I personally never missed the linear numbers. Using git to work with 
projects like cloog[1], isl[2], pluto[3], Polly, LLVM and clang I got 
used to search all the time in the history (as it is readily available 
even for offline use and it is extremely fast). As a result, looking up 
version numbers easily integrated into my work flow.

Did you try to work with git and are you convinced this is a show 
stopper for you? Or are you looking for specific solutions beyond the 
ones I have suggested?
