An even better solution would be to remove .PS and .TS completely --
most troff users would be quite irritated to see them without its
normal meaning.

Here an incomplete list of reserved keywords used by preprocessors
(not all are available for groff obviously):

  .EQ (eqn)
  .EN

  .GS (grn)
  .GE
  .GF

  .PS (pic)
  .PE

  .R1 (refer)
  .R2
  .[
  .]

  .TS (tbl)
  .TE
  .TH

  .G1 (grap)
  .G2

  .IS (ideal)
  .IE

  .cstart (chem)
  .cend

As mentioned earlier already, no macros should start with .[ and .]
at all since `refer' don't use whitespace between .[ and its argument.
