[PATCH v3 2/3] emacs: Reverse the meaning of notmuch-show-refresh-view's argument

[Austin Clements <amdragon@MIT.EDU>]

Consensus seems to be that people prefer that refreshing show buffers
retains state by default, rather than resetting it by default.  This
turns out to be the case in the code, as well.  In fact, there's even
a test for this that's been marked broken for several months, which
this patch finally gets to mark as fixed.
