tog: add support for navigating to first/last item of log and diff views
The keybindings that we settled on are Home, Ctrl-u and g to go to the first item and End, G to go to the last. This resembles those commonly found elsewhere, eg vi/less. discussed with and ok stsp
Sync the description of the -r flag from "tree" to the other commands.
Clarify that if the current directory is a work tree, tog will pick the repository associated with this work tree by default. ok stsp
make got and tog accept a --version argument; -V option is a bit obscure
