etc/committer: Speed up surrounding-sexp.
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.
