Subject: Add option to scan mailboxes during first run.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=2822b4ebc18512c7d2339a9eafe77d84988e6597;p=mutt

Add option to scan mailboxes during first run.

The scanner will disable the header cache, allowing scanning all
messages in the mailbox.
