When developers run the pre-commit, they don't always understand what to or where to find more information. The hook description field is already present and often used to provide more descriptive information. For brevity this is not shown in normal cases, but this PR changes the tool behavior to show the description in verbose mode (`-v`). So most users won't see any difference but this can easily be enabled for people who want it.
Alternatives considered:
* Always show the description: Some people may not like this though as it can be spammy.
* Provide a new field: Possible but seems to be just more work with description already present and not otherwise used.
* Show the `repo` link. This is at the wrong level and has a slightly different purpose. Though description can just be set to the same url where that is correct.
When git status runs in a repo with submodules, it'll recursively run
git status in every submodule as well by default (sequentially).
git status is substantially slower on Windows than on Linux. git diff
behaves similarly to git status in terms of running recursively within
all submodules. In repos with hundreds of submodules, this quickly adds
up when git status/diff are called multiple times. Pre-commit runs
git status once at the beginning of an operation and then runs git diff
before and after each hook. These calls quickly add up and make
pre-commit unusable in large repos with lots of submodules.
This commit drastically improves performance in repos with lots of
submodules and fixes#1701 by telling git status and git diff to ignore
submodules. This change is not expected to have any negative effect on
existing hooks because each submodule should manage its own hooks
instead of relying on superproject hooks to manipulate their contents.
If using the prepare-commit-msg and commit-msg stages specifically (such
as with the try-repo command), the `--commit-msg-filename` arg must be
provided.
