How to get prefix with quotes in completion widgets?

["Ebourne, Martin" <martin.ebourne@csfb.com>]

Hi,

How do I get access to a version of $PREFIX which includes the quotes within a completion widget?

eg. If I have a completion widget for example which prints the following:

	echo "il:$words:"
	echo "ll:$words[1,CURRENT-1]:"
	echo "pr:$PREFIX:"
	echo "ip:$IPREFIX:"
	echo "qi:$QIPREFIX:"
	echo "aq:$compstate[all_quotes]:"

And then I enter the line:

example insert ( 'foo', 'bar' )
                        ^^^
                        123

And complete on the three successive characters shown, I get:

1:
	il:example insert ( 'foo', 'bar' ):
	ll:example insert:
	pr:(\ foo,\ :
	ip::
	qi::
	aq:\:
2:
	il:example insert ( 'foo', 'bar' ):
	ll:example insert:
	pr:(\ foo,\ :
	ip::
	qi::
	aq:\:
3:
	il:example insert ( 'foo', 'bar' ):
	ll:example insert:
	pr:(\ foo,\ b:
	ip::
	qi::
	aq:\:

Here PREFIX has lost the ' which are present in words[CURRENT]. Is there a way to access a version of PREFIX which has not been so altered? Or alternatively, is there a way of getting the character position of the cursor inside words[CURRENT] so that I could use that?

I note especially that although the cursor is in a different position for 1 & 2 (1: outside the quote, 2: inside the quote), there is no difference in the information available at completion time that I can see.

Cheers,

Martin.
