Subject: lib-index: Make sure new dovecot.index.log files start tracking modseqs.
X-Git-Tag: 2.3.0.rc1~3053
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1ff03d2244dd08effadfecec365bec28793a1aa0;p=thirdparty%2Fdovecot%2Fcore.git

lib-index: Make sure new dovecot.index.log files start tracking modseqs.

This will make mail_index_modseq_get_next_log_offset() work correctly even
if modseqs haven't been explicitly enabled.
