  I think not.  I checked the cat page file that was produced after
issuing the info and man commands (deleting the cat file after
checking).  These commands result in cat page files with different
control characters.

  "info" results in a cat page file containing the control character ^H
(BS, backspace), but the file from "man" contains escape sequences like
"ESC[1m...ESC[0m"  (for bold, and eventually dependent on TERM)

  I think that root always produces a cat page file, when man is run.

I use man version 2.6.2-1.
