When artist has begin and end date set to the same year (with no months and days), then it's shown as lasting "0 days". Should be something like "A few months", "Under a year" or "1 year or less" imo.
Some examples (http://musicbrainz.org/search?query=begin:2010+AND+end:2010&type=artist&advanced=1) http://musicbrainz.org/artist/4e9c81e5-30e9-44ab-8b85-950d83b80df3 http://musicbrainz.org/artist/785e1c02-f535-4fc0-a1d6-23de849ebdcb http://musicbrainz.org/artist/8205c65a-8c87-4a4b-91e2-b63861283d41 http://musicbrainz.org/artist/d79e9c45-cc83-48f9-a8d1-16b6e74a65e6
Or we display nothing for those, maybe. Instead of
Founded: 2010 Dissolved: 2010 (0 days)
we would have
Founded: 2010 Dissolved: 2010
Or even
Founded and Dissolved: 2010
This seems to be resolved with my MBS-5250 work
