mdiff: fix diff -b/B/w on mixed whitespace hunks (issue127)

Previous code was computing hunks then checking if these hunks could be ignored
when taking whitespace/blank-lines options in accounts. This approach is simple
but fails with hunks containing both whitespace and non-whitespace changes, the
whole hunk is emitted while it can be mostly made of whitespace. The new
version normalize the whitespaces before hunk generation, and test for
blank-lines afterwards.

#!/bin/sh

hg init repo
cd repo

echo a > a
hg ci -qAm 'add a'

echo b > b
hg ci -qAm 'add b'

hg up -qC 0
hg rm a
hg ci -m 'rm a'

hg up -qC 1
rm a

echo '% local deleted a file, remote removed'
hg merge # should fail, since there are deleted files
hg -v merge --force
echo % should show a as removed
hg st

hg ci -m merge
echo % manifest. should not have a:
hg manifest
