[PATCH] Use git commit --only

[Luis Ressel]

Pass the name of the file being committed to "git commit". This way, git
will only commit the change to the password file which has been changed,
even if the password store happens to be part of a larger git repository
and other (completely unrelated) files are staged.

Adding the "--only" option isn't strictly neccessary; even without it,
"git commit" would behave in this way when it's passed file names as
arguments. For clarity, I've chosen to add the option regardless.
