Added a small change to the .magicrc startup file to get rid of
any tilde notation in the definition of environment variable
PDK_ROOT.  This allows files from the PDK to be marked with
$PDKPATH in .mag files when the PDK has been installed in a
user's local filesystem and PDK_ROOT contains tilde notation.
