The gpg-agent(1) man page has a word-wrapping issue: in the FILES
section, from the "gpg-agent.conf" text up to, but not including,
the last paragraph ("Note that on larger installations..."), the
text is not formatted correctly, at least with a 80-column
terminal or narrower.

Here's what I obtain with a 68-column terminal (I've reduced it
to 68 for the purpose of the bug report):

       gpg-agent.conf
                This  is  the  standard configuration file read by
              gpg-agent on
                startup.  It may contain any  valid  long  option;
              the leading
                two  dashes  may not be entered and the option may
              not be abbreviated.
                This file is also read after a SIGHUP however only
              a few
                options  will  actually  have an effect.  This de‐
              fault name may be
                changed on the command line  (see:  [option  --op‐
              tions]).
                You should backup this file.

I suppose that the cause is the two spaces at the beginning of
each line in the troff file (this doesn't occur before):

.B  gpg-agent.conf
  This is the standard configuration file read by \fBgpg-agent\fR on
  startup.  It may contain any valid long option; the leading
  two dashes may not be entered and the option may not be abbreviated.
  This file is also read after a \fBSIGHUP\fR however only a few
  options will actually have an effect.  This default name may be
  changed on the command line (see: [option --options]).
  You should backup this file.

And concerning the "Before entering a key into this file..." paragraph,
it remains formatted as in the troff file, without word-wraps for this
narrow terminal. For this issue, I don't have an idea of the cause
(perhaps some style that has not been reset?).
