The target file is /usr/share/man/man1/ssh-agent.1.gz. The first few
lines are
.TH SSH-AGENT 1 "November 15 2015 " ""
.SH NAME
\fBssh-agent\fP
\- authentication agent
.SH SYNOPSIS
The md5sums are
$ md5sum /usr/share/man/man1/ssh-agent.1.gz
30f21b3dc30d5c081dda5482c28bee40 /usr/share/man/man1/ssh-agent.1.gz
$ zcat /usr/share/man/man1/ssh-agent.1.gz | md5sum
3bcf66fe367ed5df9c5d209b291b09cb
(Didn't want to attach the actual ssh-agent.1.gz file, figuring it would
probably get kicked out by the list handler, but it you want it, just let
me know, will send it directly to you.)

Not that I am aware of. But in any case, "man -w -W" reports only the
roff source page (the one mentioned above) but does not report any "cat"
version:
$ man -w -W ssh-agent
/usr/share/man/man1/ssh-agent.1.gz
So I think that implies that the page that gets rendered when I do
"man ssh-agent" really is from that .gz file, processed at that time
by man(1), not a cached version.
I also did this:
$ cd /tmp
$ cp /usr/share/man/man1/ssh-agent.1.gz foo.gz
$ man ./foo.gz
and the rendered result is identical to "man ssh-agent" (i.e. the
indentation oddity is present.)

My entire fileystem contains no file of either of those names, as
verified using slocate(1).

Hope the above helps. Let me know if there's anything else you need.
