switch diff output mode from "edscript" to "plain" for diff3
getchange() in diff3.c takes any line that starts with an integer and treats it as a hunk header. It doesn't actually require ed script instructions, and traditional ed script diff output would break it. Thus, changing Got's diff3 to rely on plain diff output mode paves the way for implementing traditional ed-script style output in diff.git. Patch by Tom Jones
switch 'tog diff' and 'tog blame' to Myers diff for speed
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

fix a segfault in edscript() introduced by my previous commit
Found by our cherrypick regression tests.
fix merging of files which contain a dot on a line by itself
Annoying bug which we inherited from OpenRCS which inherited it from OpenBSD's diff3 program. ok tracey millert
use Patience diff for merging during cherrypick/backout/histedit/rebase
This has been shown to prevent mis-merges in some cases. It's probably not a final solution. We should look at what Git's "recursive merge" is doing and implement something similar. Keep using Myers during update/unstage. The advantage of Myers is that it produces smaller conflict chunks, and there are no known cases of mis-merges which affect update/unstage.
