I like the balance between having a documented "quote task" data structure that can be constructed manually, while having constructor functions for the POSIX, PCRE and GNU cases, so as to make casual use risk-free. The only thing I find confusing is the "multibyte" flag, which is zero for UTF-8 text (which is a multibyte format). Did you really mean "wide character" rather than "multibyte"? -- http://rrt.sc3d.org
