[bug#52763] [PATCH] etc: Match define-public only at line start.

[Liliana Marie Prikler]

The current regexp simply matches the first occurence, which more often than
not points to the *previous* variable.

* etc/snippets/text-mode/guix-commit-message-update-package ($1): Restrict
match to beginning of line with optional indentation.
