Fix undersized result buffer in pset_quoted_string().

The malloc request was 1 byte too small for the worst-case output.This seems relatively unlikely to cause any problems in practice,as the worst case only occurs if the input string contains nocharacters other than single-quote or newline, and even thenmalloc alignment padding would probably save the day. But it'sdefinitely a bug.David Rowley
