I think it's a good idea to create a convenient interface to "git", but I wonder if it couldn't have been implemented more flexibly as a file to be sourced by "bash". The shell file would avoid the need for custom config file syntax (with the /etc default behavior "for free"), and it would allow the git interface to be sourced into running shells without creating new ones. It would be easier to support different types of shells. The file could be copied and adapted to produce interfaces for additional commands, besides "git". Given that, if you still wanted a "git-sh", you could make an alias that runs "source /path/to/the/file.bash" whenever "git-sh" is typed (or "exec bash --rcfile=...", etc.).
