Add optional parameter for changed/added/del/unknown files to commands.dodiff This makes it possible to avoid a call into repo.changes if the details of what has changed is already known

#!/bin/sh

hg init
echo This is file a1 > a
hg add a
hg commit -m "commit #0" -d "0 0"
touch b
hg add b
rm b
hg commit -A -m"comment #1" -d "0 0"
