Due to the way the Makefiles are structured, there is no direct mapping between upstream and how -portable provides the same functionality. Therefore, add -Wunused-variable and -Wwrite-strings as per previous commits.

Make the choice of diff algorithm configurable by diff API users. The got and gotweb programs keep using Patience diffs which are prettier than Myers. But tog should be as fast as possible since it is being used interactively. If performance of Patience diff gets improved later we can consider switching tog back over to it. ok tracey jamsek

Account for the border so we don't scroll offscreen, and don't unset the load_all flag till all commits have been loaded so we take the correct path in log_move_cursor_down(). ok stsp@

Enable all main views to open primary child views in a horizontal split: log -> diff tree -> blame blame -> diff ref -> log Support is yet to be expanded to nested child views and key maps for manipulating split type and size. ok op@ and stsp@

Simplify the log input handler by moving (page)up/down and home/end logic into helper routines as we need to perform some checks on these cases when navigating the log view in horizontal splits. ok op@ and stsp@

Reported by jamsek: $ tog # term wide enough to vsplit return # open commit f # fullscreen commit tab # should go to fullscreen log, but it splits the screen fix ok jamsek

Throwing this into the mix for a while, we can always get rid of it again if it becomes annoying. No objections from stsp@

The idea is that got patch can simply look for a line such as: commit - abcde1234567... to find the merge base commit ID to show in diff3 conflict markers. got log -p now displays commit IDs in its diff header, instead ofl tree or blob IDs. ok op@
