Subject: 24.5; xsdre-translate fails on general punctuation

This seems to cause trouble:

emacs -Q
M-x load-library xsd-regexp
;; this is as expected:
(string-match (xsdre-translate "\\p{Pd}") "a-b");; 1
;; this fails:
(string-match (xsdre-translate "\\p{P}") "a-b");; nil

The regular expression produced for "\\p{P}" is faulty:

(pp (xsdre-translate "\\p{P}"))

produces:

"[!-#%-*,-/:;?@[-]_{}¡«­·»¿;·՚-՟։֊־׀׃׳״،؛؟٪-٭۔܀-܍।॥॰෴๏๚๛༄-༒༺-༽྅၊-၏჻፡-፨᙭᙮᚛᚜᛫-᛭។-៚ៜ᠀-᠊‐-‧‰-⁃⁅⁆⁈-⁍⁽⁾₍₎〈〉、-〃〈-】〔-〟〰・﴾﴿︰-﹄﹉-﹒﹔-﹡﹣﹨﹪﹫！-＃％-＊，-／：；？＠［-］＿｛｝｡-･]"


I guess the problem is the sequence "[-]" in the regex that closes the
opening "[".  This is noticeable in that it breaks validation with many
rng schemas that use the "P" character class.


The result of (xsdre-translate "\\p{P}") should look something like
this, I suppose:

"[][!-#%-*,-/:;?@[_{}¡«­·»¿;·՚-՟։֊־׀׃׳״،؛؟٪-٭۔܀-܍।॥॰෴๏๚๛༄-༒༺-༽྅၊-၏჻፡-፨᙭᙮᚛᚜᛫-᛭។-៚ៜ᠀-᠊‐-‧‰-⁃⁅⁆⁈-⁍⁽⁾₍₎〈〉、-〃〈-】〔-〟〰・﴾﴿︰-﹄﹉-﹒﹔-﹡﹣﹨﹪﹫！-＃％-＊，-／：；？＠［-］＿｛｝｡-･-]"

Yup.  I've now fixed this in Emacs 28.
