+Subject: [PATCH 1/3] gregex: Handle PCRE2_ERROR_MISSING_NUMBER_TERMINATOR if
+ defined
+
+When the error is defined in a new enough PCRE2 we should handle it.
+
+However let's not define an error message for this in this commit (just
+let's use the old one that is generic enough), so that it can be backported
+to stable versions without having to require new translations.
+
+Closes: #3809
