diff-format doc: a score can follow M for rewrite

b6d8f309 (diff-raw format update take #2., 2005-05-23) started documenting the diff format, and it said ... (8) sha1 for "dst"; 0{40} if creation, unmerged or "look at work tree". (9) status, followed by similarlity index number only for C and R. (10) a tab or a NUL when '-z' option is used. ... because C and R _were_ the only ones that came with a number back then. This was corrected by ddafa7e9 (diff-helper: Fix R/C score parsing under -z flag., 2005-05-29) and we started saying "score" instead of "similarlity index" (because we can have other kind of score there), and stopped saying "only for C and R" (because Git is an ever evolving system). Later f345b0a0 (Add -B flag to diff-* brothers., 2005-05-30) introduced a new concept, "dissimilarity" score; it did not have to fix any documentation. The current text that says only C and R can have scores came independently from a5a323f3 (Add reference for status letters in documentation., 2008-11-02) and it was wrong from the day one.
