Description

XSLT 3.0 allows the regex in xsl:analyze-string to be one that matches a zero length string, but Saxon-JS is not handling this correctly. It fails with Error SXJS0004 and the message "looping???". XSLT 3.0 test cases analyze-string-090b and -091b fail.

Fixed on the 2.0 branch in Expr.analyze by adding the code

        if (result[0].length === 0) {

            pattern.lastIndex++;

        }

I've left the test for looping in the code, just in case.
