From: Tom Tromey <tom <at> tromey.com> To: bug-gnu-emacs <at> gnu.org Subject: 25.0.50; vc-change-log displays "show 2x entries" even when none available Date: Wed, 05 Nov 2014 12:23:40 -0700
I did "C-x v l" on a file with 5 revisions.
They all appear in *vc-change-log*.
At the bottom I see two buttons:
Show 2X entries Show unlimited entries
First, there aren't any more entries, so showing these buttons is
confusing. That's somewhat understandable but it would be nice if it
didn't do that.
Clicking "Show 2X entries" shows the same data -- and the buttons
reappear. In this case the buttons definitely should not show up.
Clicking "Show unlimited entries" does the right thing -- the buttons go
away.
This behavior is more confusing when the entries don't fit in the
window. Then it isn't obvious if clicking the button actually got more
entries or not.
