This is a good idea. But I notice that -M, -C, -B can take
a diverse set of option forms, including floating point and
optional "%". "-B" can take two args, separated by a "/".
See diff_scoreopt_parse(). It would be weird for git-p4 to limit
that set to integers like you do here.
Would you be willing to change it to pass the string blindly?
Just filter out the special values, and pass everything else
unchanged.
"true" -> "-M"
"false" -> ""
"" -> ""
".*" -> "\1"
Dunno if you care about --break-rewrites. Just pointing to it
as a similar option to -M and -C in case you missed it.
