    (description
     "In 2002, Sam Williams wrote Free as in Freedom, a biography of Richard
M. Stallman.  In its epilogue, Williams expressed hope that choosing to
distribute his book under the GNU Free Documentation License would enable and
encourage others to share corrections and their own perspectives through
modifications to his work.  Free as in Freedom (2.0) is Stallman's revision of
the original biography.  While preserving Williams's viewpoint, it includes
factual corrections and extensive new commentary by Stallman, as well as new
prefaces by both authors written for the occasion.  It is a rare kind of
biography, where the reader has the benefit of both the biographer's original
words and the subject's response.")

When using // we assume that the package definition's S-expression is a
nesting of proper lists.  This is not guaranteed to be true, because a package
definition may contain alists.  By using an explicit path to the field of
interest we avoid recursion through all child nodes, thus avoiding child nodes
that are more likely to contain improper lists.

* etc/committer.scm.in (change-commit-message): Replace // with a path for the
PACKAGE symbol.

<tr class='nohover-highlight'><td/><td colspan='3' class='logmsg'>
The old surrounding-sexp procedure would read all S-expressions from the
beginning of the file up to the given line number and then return the last
encountered S-expression.  This is quite wasteful.  Instead we can record all
lines that begin with an S-expression and jump straight to the offset closest
to the desired line number to read the S-expression there.

* etc/committer.scm.in (lines+offsets-with-opening-parens): New procedure.
(surrounding-sexp): Use it.
