[PATCH 0/1] Enabling header caching in mutt

[Leo Famulari]

This patch builds mutt with support for header caching so that large
mailboxes can be opened quickly.

Without the header cache, each message's headers are processed before
the mailbox can be used. For large mailboxes (>10000 messages), this can
take minutes.

To use the header cache, users must enable it in their configuration.

It's following up on this:
http://lists.gnu.org/archive/html/help-guix/2016-03/msg00055.html

I checked, and bdb and gdbm are already both in mutt's build-time
dependency graph (openldap refers to bdb and python refers to gdbm).

I've chosen gdbm for it's small size and because it's a GNU project. If
anyone says they prefer another database, then let's talk!

I don’t use Mutt but this LGTM!

Maybe add “for header caching” as a margin comment.

Thanks,

I've just tried this out on my machine. At first I didn't see any
change, but then I added `set header_cache = ~/.cache/mutt/` to my
.muttrc and I was blown away by the difference.
