This procedure reads the characters from the underlying file "%lineedit"

statement is defined as one or more P.S. tokens terminated by a newline,
such that no '{' or '(' is left unmatched. This procedure should
only be called from the %statementedit fillbuff routine. After reading
a newline character, the lineedit file must be reopened if further
characters are required to complete the statement.
