That is because of those [0-9] to [1-9] changes which prevent
basepoints/gcc-0 from working.  While basepoints/gcc-005 etc. are certainly
unexpected, basepoints/gcc-0 needs to work.

2022-03-10  Jakub Jelinek  <jakub@redhat.com>

	PR other/102664
	* git-descr.sh: Replace all [1-9] occurrences with [0-9].
	* git-undescr.sh: Likewise.
