convert: mercurial_source: also search for copies in modified files

There are some corner cases where we may have a copy in a file that
isn't in the added list:

- the result of a hg copy --after --force

- after a merge across a (local) rename

#!/bin/sh

echo "[extensions]" >> $HGRCPATH
echo "hgext.convert=" >> $HGRCPATH

hg init orig
cd orig

echo foo > foo
echo bar > bar
hg ci -qAm 'add foo bar' -d '0 0'

echo >> foo
hg ci -m 'change foo'

hg up -qC 0
hg copy --after --force foo bar
hg copy foo baz
hg ci -m 'make bar and baz copies of foo' -d '1 0'

hg merge
hg ci -m 'merge local copy' -d '2 0'

hg up -C 1
hg merge 2
hg ci -m 'merge remote copy' -d '3 0'

hg convert --datesort orig new 2>&1 | grep -v 'subversion python bindings could not be loaded'
