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

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"?
