Title:
  perldoc shows lots of escapes

Status in perl package in Ubuntu:
  Confirmed

Bug description:
  Fresh konsole:
  $ echo $TERM
  xterm-256color
  $ type perldoc
  perldoc is /usr/bin/perldoc
  $ dpkg -S /usr/bin/perldoc
  diversion by perl-doc from: /usr/bin/perldoc
  diversion by perl-doc to: /usr/bin/perldoc.stub
  perl, perl-doc: /usr/bin/perldoc
  $ echo $PAGER

  $ perldoc perlsyn

  (Now in pager:)

  ESC[1mNAMEESC[0m
      perlsyn - Perl syntax

  ESC[1mDESCRIPTIONESC[0m
      A Perl program consists of a sequence of declarations and statements which
  ...

  That's a lot of ESCapes.  PAGER=more gets me "2NAME2" and the like.

  $ locate perlsyn
  /usr/share/man/man1/perlsyn.1.gz
  /usr/share/man/man1/perlsynology.1.gz
  /usr/share/perl/5.26.0/pod/perlsyn.pod
  /usr/share/perl/5.26.0/pod/perlsynology.pod

  No cached files apparently.

  This works reasonably: TERM=none perldoc perlsyn | (TERM=vt100 less) -
  but looses the bolds etc.

  This works well: man perlsyn

  This also works as expected, showing bolds and stuff, but I find it impractical:
      perldoc perlsyn | cat

  So perldoc applies terminal appropriate escapes where it should not?
