Key fonts fix to Mathematica 4.2 upgrade instructions

I just noticed a likely problem for those folks *upgrading* to
Mathematica ("Mathematica")4.2 from earlier versions.

In Mathematica 4.1 and earlier, the special Mathematica truetype fonts had names like
"math1", etc. In Mathematica 4.2, they have been (evidently) superceded by new
fonts with new namings like "mathematica1", etc.  The *upgrade*
instructions direct one to run the uninstaller on Mathematica 4.1 (or earlier)
after installing/verifying Mathematica 4.2. Unfortunately, that uninstall
evidently removes the old pre-4.2 fonts from Windows/Fonts (or
WINNT/Fonts).  That's a problem if one has exported/copy-pasted
graphics from earlier notebooks into powerpoint documents, etc --
those exported graphics now refer to non-existent fontnames (unless
they were originally embedded into such document)!

The workaround is obviously to marshall (copies of) the pre-4.2 fonts
out from the fonts directory before running the pre-4.2 uninstaller,
then re-install these fonts via Window/Fonts's File->InstallNewFont.
But of course, without foreknowledge of this, it'll be too late,
forcing one to grab them from pre-4.2 Mathematica CDs (a pain).

On a related note, I notice that the new 4.2 truetype fonts still have
their  internal "font-rights-privileges" flags set to "editable"
rather than "installable", which plays havoc with attempts to embed
such fonts within external docs (such as Adobe Distiller working on
Mathematica-exported graphics). The commercial Font Creator Program allows one
to readily modify these font files by flipping this flag (which from
earlier interactions was fine by WRI).
