Documentation

The splitting strategy applied to the keys in gnus-registry-track-extra.

Given a set of unique found groups G and counts for each element of G, and a key K (typically sender or subject):

When nil, if G has only one element, use it. Otherwise give up. This is the fastest but also least useful strategy.

When majority, use the majority by count. So if there is a group with the most articles counted by K, use that. Ties are resolved in no particular order, simply the first one found wins. This is the slowest strategy but also the most accurate one.

When first, the first element of G wins. This is fast and should be OK if your senders and subjects don't "bleed" across groups.
