And realistically, requiring Bash is not all that much of a problem when
targeting developers.

After thinking about this more, I am a lot less opposed to including this
in Git's source code. However, as it is not necessary for Git's
functionality, it should probably go into contrib/, and I would much
rather have a more descriptive name such as
contrib/bash-debugging-library/...
