--- Comment #1 from Petr Pisar ---
I cannot reproduce it on Fedora 23:
TERM=xterm
LESSOPEN=|/usr/bin/lesspipe.sh %s
ncurses-5.9-21.20150214.fc23.x86_64
ncurses-libs-5.9-21.20150214.fc23.x86_64
xterm-318-2.fc23.x86_64
less-481-1.fc23.x86_64
perl-Pod-Perldoc-3.25-347.fc23.noarch
Though I admit some people sometimes complained about the same issue. I would
welcome reliable reproducer.
To the question: Yes, perldoc has "-t" argument that disables ANSI sequences on
the output. I think "perldoc --help" is not so hard way to discover it.
I can fairly reproduce it with "perldoc -T perlreref | less". The capital -T
prints the output to stdout instead of sending it to a pager. But the perldoc
(that I have, the behavior changes with various perldoc versions) feeds the
pager from a temporary file. strace shows:
[pid 3367] execve("/usr/bin/less", ["less"], ["XDG_VTNR=1",

I suspect perldoc sets LESS=-R. I dont' have the variable in my environment:
$ set |grep LESS
LESSOPEN='|/usr/bin/lesspipe.sh %s'
"perldoc -T perlreref | LESS=-R less" works for me.
From my point of view, perldoc is fine in Fedora. This is issue in RHEL-7's
perldoc.
