[PATCH] PublicInbox::Feed owns `feedmax' default value

[Eric Wong <e@80x24.org>]

There's no need to have extra code in the Inbox package for this
or to waste dozens of bytes for every Inbox object which uses
the default value.

This makes our code more flexible w.r.t Inbox-like ExtSearch
objects and fixes uninitialized value warnings with ->ALL.
