tmac/an-old.tmac: Add '.na' to macro '.TS' and '.ad' to macro '.TE'

  "tbl" manages the adjustment of margins on its own.

  An external or default adjustment setting can cause a warning, like

"cannot adjust line at both margins"

  for example in

  test-nroff -man -z man/groff_char.7.man

troff: backtrace: file 'groff_char.7.man':1545
troff: groff_char.7.man:1545: warning [p 10, 9.8i]: cannot adjust line at both
margins
troff: backtrace: file 'groff_char.7.man':1546
troff: groff_char.7.man:1546: warning [p 10, 10.0i]: cannot adjust line at
both margins
