diff-format.adoc: 'git diff-files' prints two lines for unmerged files

Since 10637b84d9 (diff-files: -1/-2/-3 to diff against unmerged stage., 2005-11-29), for unmerged entries 'git diff-files' print both an "unmerged" line ('U'), as well as an "in-place edit" line ('M') comparing stage 2 (by default) with the working tree. The "Raw output format" documentation however mentions that all commands print a single line per changed file. Adjust diff-format.adoc to also mention this special case, for completeness.
