convert: workaround for cvsps.cache under Windows
In non-cygwin environment, cvsps fails to create its cache directory and redirect its output to stderr. Just ignore the error and capture stderr as well.
#!/bin/sh
"$TESTDIR/hghave" git || exit 80
echo "[extensions]" >> $HGRCPATH
echo "convert=" >> $HGRCPATH
mkdir git-repo
cd git-repo
git init-db >/dev/null 2>/dev/null
echo a > a
git add a
git commit -m t1 >/dev/null 2>/dev/null || echo "git commit error"
echo b >> a
git commit -a -m t2 >/dev/null || echo "git commit error"
cd ..
hg convert git-repo
