Subject: emacs/tree: return true if a thread was found in next-thread
X-Git-Tag: archive/debian/0.30_rc0-1~66
X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=8eec15a90338afe0f1933466a90e53767a0a4ccb;hp=144cf30e2c71d57795b5fbdec10af0ef73aa01ff

emacs/tree: return true if a thread was found in next-thread

This will allow us to pop back to parent buffers when there are no
more threads to jump to.
