bug#48037: 28.0.50; add-change-log-entry does not detect name with digit

[Michael Albinus]

In test/infra/gitlab-ci.yml, there are entries like

--8<---------------cut here---------------start------------->8---
build-native-bootstrap-speed2:
  stage: slow
...
--8<---------------cut here---------------end--------------->8---

If I change such an entry, and try to create a ChangeLog entry via 'C-x
4 a', this entry is not recognized due to the digit in its name. I
propose the following patch, which improves this:

--8<---------------cut here---------------start------------->8---
diff --git a/lisp/vc/add-log.el b/lisp/vc/add-log.el
index 6b38806651..d2d4e31d05 100644

   "Heuristic regexp used by `add-log-current-defun' for unknown major modes.
 The regexp's first submatch is placed in the ChangeLog entry, in
 parentheses."

Comments?

Best regards, Michael.
