Fix how setup.py identifies the Mercurial version.

There is a problem with setup.py where it will not identify the Mercurial
version properly when not being ran in within a repository even if
mercurial/__version__.py exists.

To fix, use mercurial.__version__.version when available before defaulting
to "unknown".  (Using mercurial.util.version() is not an option due to a
dependency issue where osutil can be referenced before it is built.)

#!/bin/sh

cat > patchtool.py <<EOF
import sys
print 'Using custom patch'
if '--binary' in sys.argv:
    print '--binary found !'

cd a
echo a > a
hg commit -Ama -d '1 0'
echo b >> a
hg commit -Amb -d '2 0'

# This test check that:
# - custom patch commands with arguments actually works
# - patch code does not try to add weird arguments like
# --binary when custom patch commands are used. For instance
# --binary is added by default under win32.

echo % check custom patch options are honored

hg clone -r 0 a b

hg --cwd b import -v ../a.diff
