On Python2, write doesn't return anything. Discard the output for
compatabilities sake.

- Tried to add the all extra requirement but it didn't install netaddr.
- Add netaddr manually.

Both in git and in the package manifest.

- Change the `run` filter to be a function. Usage should be nicer now:
  `{{ run(['id', '-u'])['stdout'] }}`. Keep the filter for a few
releases to avoid breakage.
- A few filters were missing from the README, add the documentation.

This reverts commit 30421d6e. I think
this causes the README render failure in `twine check` but I'm not sure
since I can't reproduce it locally. The clue I'm going by is the other
error about missing long_description_content_type.

Make it more explicit, set a release that will break backward
compatibility. Also, disable the proselint pre-commit hook, it can't
skip code blocks and there's not a lot I can do about that.

It's pretty much an in-place replacement but bumpversion is not
maintained anymore and bump2version is.

No longer supported by upstream.

It's autogenerated everytime I use pipenv. I don't really need it since
I'm targeting old Python and Pip versions that even know about it. The
build system declared is setuptools which is what will be used anyway.
But I grow tired of always deleting the file (adding it to .gitignore
doesn't work because check-manifest complains). I _really_ hope it won't
break anything (if it will it will probably be in new Pip versions so I
will probably see it, I hope).

Update the lock file. Mainly just to shut up the dependabot in GitHub.

I've been trying out lgtm.com and that's the only issue it found. Valid
comment, fix the issue.

It did find a spelling error in the README. What an embarssment. Correct
that as well.

Didn't find any new issues, but let's keep it for now.

The pre-commit warnings has been annoying enough. The last tag in that
repo is pretty old (2018) and doesn't have the pre-commit hook, so let's
go with the last commit which happens to be adding the pre-commit hook.
Happy coincident.

I don't know why, but the daily download count is down from 250+ to ~30.

Get the latest snippet from GitLab. Add a hook for check .gitlab-ci.yml,
remove duplications (prospector already runs a few other linters).

Forgot to exit after printing the version. Without a TTY it would exit
anyway, but in an interactive console it hangs.

A bunch of new filters based the netaddr library. Requires installing
with the package specifier.

Silent dependabot in GitHub.

A bunch of filters that just wrap objects from the netaddr library.

After 615a59a5, you need to use
specifiers to install all of the dependencies. Use the all specifier in
tests.

A quirk of GitHub, without a target the image causes a line break.

This reverts commit babd0599.
