bool AbbrevCommit get; set;
Not implemented
Instead of showing the full 40-byte hexadecimal commit object
name, show only a partial prefix. Non default number of
digits can be specified with "--abbrev=" (which also modifies
diff output, if it is displayed).
+
This should make "--pretty=oneline" a whole lot more readable for
people using 80-column terminals.
bool M get; set;
Not implemented
By default, differences for merge commits are not shown.
With this flag, show differences to that commit from all
of its parents.
+
However, it is not very useful in general, although it
*is* useful on a file-by-file basis.
