[Emacs-diffs] master a697d1e: Minor xml.el tweaks

[Paul Eggert]

branch: master
commit a697d1e638eabdb3eb32337fde6d802ef712eaf8
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>

    Minor xml.el tweaks
    
    * lisp/xml.el (xml-name-start-char-re, xml-name-char-re):
    No need to call concat.
    (xml-name-char-re): Use \u escapes rather than chars inline,
    so that the code matches the comments better and is easier
    to audit.
