void e_sexp_encode_bool (GString *s, gboolean state);
Encode a bool into an s-expression s
. Bools are
encoded using t f syntax.

|
void e_sexp_encode_string (GString *s, const char *string);
Add a c string string
to the s-expression stored in
the gstring s
. Quotes are added, and special characters
are escaped appropriately.
