Git prevision

Need to quickly check a previous version of a specific file?...
Do not want to switch the entire repository to an older commit and back?...

A combination of git aliases/awk/shell-functions to the rescue

Here is a quick and intuitive way to checkout a older version of a single file in git.

Basically the command does a git log on the specified file and picks the appropriate commit-id in the history of the file and then runs git checkout to the commit-id for the specified file.

Essentially, all that one would manually do in this situation, wrapped-up in one beautiful, efficient git-alias - git-prevision
