tests/test-merge4

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"
echo This is file b1 > b
hg add b
hg commit -m "commit #1" -d "0 0"
hg update 0
echo This is file c1 > c
hg add c
hg commit -m "commit #2" -d "0 0"
hg update -m 1
rm b
echo This is file c22 > c
hg commit -m "commit #3" -d "0 0"
