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
for i in aaa zzz; do
hg init t
cd t
echo "-- With $i"
touch file
hg add file
hg ci -m "Add"
hg cp file $i
hg ci -m "a -> $i"
hg cp $i other-file
echo "different" >> $i
hg ci -m "$i -> other-file"
hg cp other-file somename
echo "Status":
hg st -C
echo
echo "Diff:"
hg diff -g
echo
cd ..
rm -rf t
done
