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.

import os, sys
from mercurial import hg, ui

TESTDIR = os.environ["TESTDIR"]

# only makes sense to test on os which supports symlinks
if not hasattr(os, "symlink"):
    sys.exit(80) # SKIPPED_STATUS defined in run-tests.py

# this is what symlink would do on a non-symlink file system
def symlink_failure(src, dst):
    raise OSError, (1, "Operation not permitted")
os.symlink = symlink_failure

# now try cloning a repo which contains symlinks
u = ui.ui()
hg.clone(u, os.path.join(TESTDIR, 'test-no-symlinks.hg'), 'test1')
