`git-commit': fix variable predicates

Browse source 
`git-commit-summary-max-length' should be a number, not a symbol.

`git-commit-major-mode' should be checked more carefully, as otherwise
exploits are possible (e.g. if it is `erase-buffer' or some more
dangerous function of the user's environment).
