gdb-13.2 is being planned but it won't be out for a little while yet. As noted in the commit messages for these 13.1.90* versions, they're really snapshots from the stable branch and it's just easier than cherry-picking commits. So, let's stable this instead of 13.1 itself, to avoid breaking stuff just for a nicer looking version number.
