Tig dies with error message when spamming G in main view

[h3xx]

Tig version: 88962f1
Git version: 2.6.4
Slackware Linux (x86_64)
Xterm

Steps to reproduce:

1. Clone any git repository with a fair amount of history (jonas/tig works nicely).

   $ git clone https://github.com/jonas/tig.git
   $ cd tig

2. Increase X11 keyboard repeat rate to something quick but manageable:

   $ xset r rate 145 45

3. Open tig to the main view inside the git repo:

   $ TIGRC_USER=/dev/null tig

4. Spam G a few times (hold down Shift+g)

Outcome:

Tig flashes a few times, then exits back to the prompt with the following error message:

tig: No revisions match the given arguments.

The flashes are because it's executing :toggle commit-title-graph and redrawing the digraph.

Trace output:

Thanks for reporting this. Should be fixed even if it is a strange corner case.

Confirmed fixed. Tested version 3ce0631 (2016-04-19).

Thanks!
