Ah...  But bash doesn't clean up the path for it's own children.  So
actually that does not work.  Or works only in a restricted subset.
Because if the command executed invokes other commands those other
commands will get PATH with a ~/ in it and unless they also decode
that syntax they might fail.

So beware.  Switched it back to the full path in PATH without the ~/
in it.  And should file a bug against the crontab(5) man page about
the problem too.
