#3264 fixes a security blunder by eliminating support for path expressions of the form:
{{python statements}}
As compensation, the PR supports
Python's standard syntax defined by os.path.expanduser and os.path.expandvars.
Those who now use path expressions must replace them with the standard syntax. A global search/replace should suffice.
This PR will be the highlight of Leo 6.7.3, scheduled for a few days from now. Please test this PR and report any problems.
