Fix handling of paths when run outside the repo. The main problem was that dirstate.getcwd() returned just "", which was interpreted as "we're at the repo root". It now returns an absolute path. The util.pathto function was also changed to deal with the "cwd is an absolute path" case.

hg init foo
cd foo

A=`echo -e -n 'he\rllo'`

echo foo > "hell
o"
echo foo > "$A"
hg add
hg ci -A -m m
rm "$A"
ls
hg add
# BUG ? we don't walk on filenames with '\n' (regexp related) ?
hg debugwalk
hg ci -A -m m

exit 0
