Subject: emacs: show: use interactive instead of current-prefix-arg
X-Git-Tag: 0.17_rc1~102
X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=99d474c484d89d3436c910f1ac447640c533e811

emacs: show: use interactive instead of current-prefix-arg

Currently notmuch-show looks at the prefix-arg directly via
current-prefix-arg. This changes it to use the interactive
specification.

One test (for elide-toggle functionality) set the prefix arg
directly. Update this test to set the new argument directly.
