Hi all,

scan-sexps throws an error if it cannot move as many sexps as I want.
This is fine in interactive use, but not really helpful in Lisp code I’m
writing.  (For the curious: I’m trying to write a solid SLOC-counting
function, and I need moving by sexps to determine whether a string is
a docstring, which I want to exclude from the count.)  Any ideas what to
do?  I could rewrite it in Elisp, but is it a good idea?  I doubt so.

NB. I don't really use scan-sexps, I use backward-sexp, which is
seemingly a higher level function – but, unlike search functions, it
doesn't have a “noerror” argument.
