|
** A: addition of a file
|
** C: copy of a file into a new one
|
** D: deletion of a file
|
** M: modification of the contents or mode of a file
|
** R: renaming of a file
|
** T: change in the type of the file
|
** U: file is unmerged (you must complete the merge before it can be committed)
|
** X: "unknown" change type (most probably a bug, please report it)
|
**
|
** Status letters C and R are always followed by a score
|
** (denoting the percentage of similarity between the source and target of the move or copy).
|
** Status letter M may be followed by a score (denoting the percentage of dissimilarity) for file rewrites.
