Hg split ?

[Peter Arrenbrecht]

I did take a look now because I needed something similar: Breaking up
an existing hg mq patch into multiple patches. I did not manage using
filterdiff because it will strip out the "diff --git ..." lines and
binary diffs from the patches. The former could easily be addressed
with a filterdiff option to copy n additional lines _before_ a new
file start. The latter is a little harder. I am considering adding
this to filterdiff or else write an hg filterdiff extension that does
this.
