hgweb: fix filediff base calculation

Previously, we were finding the most recent version of a file in a
changeset and comparing it against its first file parent. This was
wrong on three counts:

- it would show a diff in revisions where there was no change to a file
- it would show a diff when only the exec bit changed
- it would potentially compare against a much older changeset, which
  could be very expensive if git-style rename detection was enabled

This compares the file in the current context with that context's
parent, which may result in an empty diff when looking at a file not
touched by the current changeset.

f = open('test.py', 'w')
try:
    f.write('foo\n')
finally:
    f.close

print '% add and commit'
add(u, repo, 'test.py')
commit(u, repo, message='*')
status(u, repo, clean=True)


print '% change'
f = open('test.py', 'w')
try:
    f.write('bar\n')
finally:
    f.close()

# this would return clean instead of changed before the fix
status(u, repo, clean=True, modified=True)
