hgview #9318 hgview does not show files with changed modes in diffs [validation pending]

hgview does not show files with changed modes in diffs

Reproduction steps:

sfllaw@belgium:~$ mkdir foo
sfllaw@belgium:~$ cd foo
sfllaw@belgium:~/foo$ hg init
sfllaw@belgium:~/foo$ touch me
sfllaw@belgium:~/foo$ hg add me
sfllaw@belgium:~/foo$ hg ci -m 'Added me'
sfllaw@belgium:~/foo$ chmod +x me
sfllaw@belgium:~/foo$ hg ci -m 'me is runnable'
sfllaw@belgium:~/foo$ hgview

Expected results: Both changesets indicate that an empty file has been changed, somehow. This is what hgk does.

Actual results: It looks like no changes have been made.
