The fuzz tests caught a case we were not handling when a predefined character class is used immediately after a string anchor (eg. the pattern
a\Z\V
) which caused the transpilation to be incorrect. To fix this, I moved the rewriting of character classes\s, \S, \v, \V, \h, \H
to the rewrite() stage and factored out the logic handle negated character classes(This PR contains the second half of the changes from #5522)
