`git lfs status` only outputs status for files that are pending some git-lfs related operation.
For usage with --enforce-all, we need the list of all files that are tracked, which can be
achived by `git lfs ls-files`.
Fixes: https://github.com/pre-commit/pre-commit-hooks/issues/560
The --enforce-all option when provided ensures that all files passed
on the command line are checked against the size limit. Default
behaviour remains unchanged.
1. Disable automatic `git commit` GPG-signing, since that requires interaction.
This issue was encountered in practice by me, causing spurious test failures
2. In case path operands could turn out to start with dashes, escape the
operand list with '--'.
