<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.
