Fixes <https://bugs.gnu.org/35582>. Reported by sirgazil <sirgazil@zoho.com>. Previously, leading zeros would be removed, leading to an "invalid" UUID: (uuid->string (uuid "00CA-050E" 'fat32)) ⇒ "CA-50E" (string->uuid "CA-50E" 'fat32) ⇒ #f * gnu/system/uuid.scm (fat-uuid->string): Pad digits with zeros. * tests/uuid.scm ("uuid, FAT32, leading zeros preserved"): New test.
