compat: add wrapper for obsolete.createmarkers() that accepts "operation" arg
I want to start passing the operation argument, but hg < 4.3 does not
support it, so we need a compat wrapper. For older hg, the operation
is simply ignored.
# utility to setup pythonpath to point into the tested repository
export SRCDIR=`dirname $TESTDIR`
if [ -n "$PYTHONPATH" ]; then
export HGTEST_ORIG_PYTHONPATH=$PYTHONPATH
export PYTHONPATH=$SRCDIR:$PYTHONPATH
else
export PYTHONPATH=$SRCDIR
fi
