Log message:
etckeeper: update to 1.18.21. Changes:

* Consistently use mktemp if available, falling back to tempfile
  otherwise.

Log message:
Update to 1.18.20. From the changelog:

* Added support for Gentoo (emerge, qlist, and cave)
* Skip running pre-commit hook inside linked worktrees, to avoid it
  updating .etckeeper with the permissions of files not in /etc.
* commit: Run bzr with --quiet, since it outputs non-errors to stderr.
  Closes: #1018874

Log message:
Update to 1.18.16. From the changelog:

* Improve sorting stability.
* Prefer mktemp over tempfile as the latter displays a deprecation
  warning since debianutils 4.10. Thanks, Luke Mlsna.
* Use "command -v" rather than "which" to detect installed \ 
programs, as
  it is more portable. Thanks, Eli Schwartz.
* Improve commit messages generated by package manager changes,
  listing packages that are responsible for the changed config files.
  Thanks to emkael for the patch.
* If gc.auto is not configured, override the default to make it gc
  ten times more frequently, to avoid wasting space with loose objects.
* update-ignore: Preserve permissions from any preexisting VCS ignore file.
  Thanks, Austin Chu.
* Removed the debian directory from the upstream source package as it's
  not being maintained; see the debian package for an up-to-date one.
* debian/changelog moved to CHANGELOG and debian/copyright to COPYRIGHT.

Log message:
Sort PLIST.

Log message:
Use ${EGREP} instead of whatever "egrep" happens to be at runtime. Fixes
