Huge difference between the lucene index size created by v2.1 and v2.2

[Timo Sirainen]

Actually that same header indexing behavior was already in v2.1. But I found the real problem now: http://hg.dovecot.org/dovecot-2.2/rev/febedba15c7e

That bug was actually already in v2.1, but because memory was always allocated from stack it wasn't causing as many problems.
