Previously, the script would raise an error if a copyright line was added to a
file in gnu/packages/. With this change, it will amend the previous commit
whenever a copyright line is added, and add the copyright line to the commit.
* etc/committer.scm.in (add-copyright-line): New procedure.
(main): Check if a copyright line was added and call ‘add-copyright-line’ if
necessary.

Some package definitions use G-expressions (see, e.g., chez-scheme).
Import (guix gexp) such that Guile knows how to read those.
Otherwise, an exception such as the following might be raised:
ERROR: In procedure read:
In procedure scm_lreadr: gnu/services/networking.scm:480:16: Unknown # object: #\~
* etc/committer.scm.in: Import (guix gexp).

With zero context new definitions would be applied to the wrong location in
the file. More context lines lead to larger hunks, though, so we use just one
line of context.
* etc/committer.scm.in (diff-info): Invoke "git diff" with one line of
context.
[info]: Merge line break and first line.
(lines-to-first-change): New procedure.
(old-sexp, new-sexp): Use it.
* etc/committer.scm.in (<hunk>)[diff]: Rename this field...
[diff-lines]: ...to this.
[definition?]: New field.
(hunk->patch): Join diff lines.
(diff-info): Do not join diff lines; record whether a hunk is a new
definition.
(commit-message): Rename this procedure...
(change-commit-message): ...to this.
(add-commit-message): New procedure.
(main): Handle new package definitions before changes.
* etc/committer.scm.in (commit-message): Use EQUAL? instead of EQ? to compute
differences because not all inputs may be symbols; some could be expressions.
