Subject: [PATCH] Revert "Reduce indentation depth using C99"

This reverts commit c4d20840f3487588c4a0da4397b1acb6dc83a1e5.  Even in
C99, a declaration isn't valid immediately after a label; this didn't
become valid until C2x, although gcc allows it as an extension.

Fixes https://gitlab.com/cjwatson/man-db/-/issues/2.
