eol: make the hook check all new heads, not only tip (issue2666) Report and test by Antoine Pitrou <solipsis@pitrou.net>

eol: the hook no longer requires the extension to be loaded Reading rules in the hook means we no longer need ui to be filled and do not need reposetup() to be run anymore.

eol: extract parsing error handling in parseeol()

eol: separate .hgeol parsing from merge in ui This will help refactoring the hook.

eol: remove unused argument in readhgeol()

eol: explain why reading .hgeol from the working dir is special

templates: widen the graph canvas (issue2683)

rebase: don't use util.Abort for an internal error

help: limit documentation width to at most 80 characters Reading long lines is suboptimal no matter how wide the terminal is.

merge with stable
