I'm seeing this same behavior with the gpg-agent manpage as well, for
what it's worth.

  $ man gpg-agent | grep ^NAME
  <standard input>:172: warning [p 2, 10.5i]: cannot
  adjust line
  <standard input>:172: warning [p 6, 4.8i]: cannot
  adjust line
  NAME
  <standard input>:172: warning [p 9, 10.0i]: cannot
  adjust line
  NAME
  NAME
  NAME

Grepping the file directly:

  $ zgrep NAME $(dirname $(readlink $(which gpg)))/../share/man/man1/gpg-agent.1.gz
  .SH NAME
  identified in the environment variable
  \fBLISTEN_FDNAMES\fR (see
  

Interestingly enough, gpg manpage from the same package doesn't seem to
have the issue:

  $ man gpg | grep ^NAME
  NAME
  <standard input>:1481: warning [p 19, 7.2i]: cannot adjust line

I've also copied the gpg-agent.1.gz file to a Debian system running the
same upstream version of man 2.8.3, and that has no issue. So it's
something specific to the guix version of the "man" command.


live well,
