stsp noticed that if you run 9999j in the log view, in a large enough
repo you have to wait till 9999 lines have been scrolled, or in
smaller repos until the end of the commit history.

This enables aborting the command with C-g or backspace.

I remembered both op and naddy were partial to C-g abort semantics, so
for consistency I've added C-g to the existing backspace option to abort
search and G in log view.

The diff also removes a couple trailing whitespace in tog.1
