Actually, it is somewhat worse -- we return an erroneous abbreviation in the rare case that we are trying to find the abbreviation for something we don't have, but for which we do have a matching abbreviation. For example, if we have 1234567890123456789012345678901234567890 then for every 12345678* that we don't have, we will claim the correct abbreviation is 1234568. In practice, I doubt this is a problem. But getting back to your point: yes, I agree it is a little ugly. Rewriting find_unique_abbrev would be necessary for fixing it, and I'm not sure it is worth the trouble. -Peff - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
