Two PC-AT XENIX bugs (no fixes).

[Larry Bierma]

I have run into two problems with IBM PC-AT XENIX (1.0).  

1) When trying to edit a file with "vi" I get the following message if
   the file has more than 2048 lines.

	"Out of memory saving lines for undo - try using ed"

2) In nroff/troff the "%" numbered register (current page number) is
   always 0.  This effectively breaks all the macro packages.  The "mm"
   macros that came with XENIX have been modified to keep track of
   page numbers in a different register, but still loses if you use
   the ".pn N" or ".bp N" commands.

Any fixes out there?
