I have now fixed this problem. To speed-up index lookups, eXist used
the first characters of the pattern to limit the portion of the btree
that needs to be scanned. However, in XQuery, regular expressions
match if any substring matches, so the first character of the pattern
does not need to be the first character in the string.

eXist now uses the first characters only if the regex starts with an "^" an=
chor.
