When using the -r option to generate webrevs the webrev script creates a correct webrev but the patch file that is linked from the webrev is missing changes.

Here's an examle that does the following: Creates a repository called "parent-repo", adds a commit, clones to a "child-repo", sets the push path, adds two commits and then creates a webrev.

mkdir parent-repo
cd parent-repo/
hg init
touch a.txt
hg add a.txt
hg commit -m "added a.txt"
cd ..
hg clone parent-repo child-repo
cd child-repo/
hg defpath -d
touch b.txt
hg add b.txt
hg commit -m "added b.txt"
touch c.txt
hg add c.txt
hg commit -m "added c.txt"
ksh webrev.ksh -r 0

If you run this with the latest webrev.sh script you get a webrev/index.html file that looks like this:

------ ------ ------ ------ --- New ----- Raw b.txt

    rev 1 : added b.txt

    0 lines changed: 0 ins; 0 del; 0 mod; 0 unchg

------ ------ ------ ------ --- New ----- Raw c.txt

    rev 2 : added c.txt

    0 lines changed: 0 ins; 0 del; 0 mod; 0 unchg


But the patch file "child-repo.changeset" is empty.

Changing the last line in the script above to just:

ksh webrev.ksh

Creates the same webrev/index.html file but it also creates a correct patch file.
