wl pushed a commit to branch master
in repository groff.

commit 3dc991b4733add0e48d773b01e5e83308c792751
Author: Werner Lemberg <address@hidden>

    * doc/groff.texinfo: Make PDF version compilable with makeinfo 5.x.
    
    makeinfo 5.x handles macro expansion better, which changes the way
    how an \LE macro (for a less-than sign) has to be defined.  However,
    since we can't be sure that the latest version of `texinfo.tex' gets
    used with makeinfo 5.x only, we would have to support both 4.x and
    5.x.  No idea whether this is possible at all...  For this reason,
    we now simply use @value directly instead of wrapping it into a
    macro, avoiding any issues.
