This cleans up the way calls are made into the diff core from diff-tree family and diff-helper. Earlier, these programs had "if (generating_patch)" sprinkled all over the place, but those ugliness are gone and handled uniformly from the diff core, even when not generating patch format. This also allowed diff-cache and diff-files to acquire -R (reverse) option to generate diff in reverse. Users of diff-tree can swap two trees easily so I did not add -R there. [ Linus' note: I'll add -R to "diff-tree" too, since a "commit diff" doesn't have another tree to switch around: the other tree is always the parent(s) of the commit ] Also -M<digits-as-mantissa> suggestion made by Linus has been implemented. Documentation updates are also included. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
