Subject: [PATCH] tmac/<files containing a ".nx" request>: Add a warning

  Some macro files have an '.nx' request
to avoid to have all of it read a second time.

  Add a warning to point out this unwanted situation.

  Two files, "pdfpic.tmac" and "pspic.tmac",
are automatically read,
as they are used in the file "tmac/troffrc".
