In fact, this remembering of the old path is how the original bug reporter 
restored his PATH variable when NSIS clobbered it!

On some versions of Windows, the next DOS box gets the new path.

True, but users have long PATH strings for reasons other than LilyPond.

The default version (without long-strings) of NSIS is known to lose strings 
longer that 1024 characters.  See the links at comment 8.

This problem would also affect the attempted path shortening on un-install, so 
probably we should remove that WriteRegExpandStr as well.
