open & vl-file-copy long file name bug & workaround

There seems to be a limitation on AutoLISP (ACAD 2002) opening or
copying files with a very long name + path.

I think the workaround is to use vl-file-rename and temporarily rename
the file that needs to be opened to something with a short name.

Example:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
_$ (setq x (getfiled "" "" "" 0))
"G:\\Details\\06 - Envelope\\01 Exterior Wall Types\\Cavity
Walls\\Brick Veneer\\LMF
Back-Up\\0000-brick-code-01_exterior-wall-at-slab-w-relieving-angle.det"
_$ (setq a (open x "r"))
nil
_$ (vl-file-copy x "c:/temp/xxx")
nil
_$ x
"G:\\Details\\06 - Envelope\\01 Exterior Wall Types\\Cavity
Walls\\Brick Veneer\\LMF
Back-Up\\0000-brick-code-01_exterior-wall-at-slab-w-relieving-angle.det"
_$ (vl-file-rename x "c:/temp/xxxyyy")
T
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perhaps there is some setting to avoid this problem.
