etc/committer: Teach it how to commit package removal.
* etc/committer.scm.in (hunk-types): New variable. (<hunk>): Rename hunk-definition? getter to 'hunk-type'. (diff-info): Mute a git warning by separating file names from arguments with '--'. Rename the 'definitions?' variable to 'type'. Use the 'addition type when a new package addition is detected, 'removal when removed else #f. (add-commit-message): Re-indent. (remove-commit-message): New procedure. (main)[definitions]: Make commit message conditional depending on whether it is an addition or removal. [changes]: Adjust indentation.
