gbranden pushed a commit to branch master
in repository groff.

commit 1c6f83d0ede0f16fb93ad2b315209329a4ff46be
Author: G. Branden Robinson <g.branden.robinson@gmail.com>

    [eqn] Actually set "..." on text baseline.
    
    * src/preproc/eqn/lex.cpp (troff_defs): Set the "..." token on the
      baseline, not vertically centered, aligning the actual behavior with
      what our eqn(1) man page has claimed since 2007.
    
    Apparently botched in 62248e78a3433a07c417d988b85b79817069f5b5, 6
    February 2007.  (Actually in two ways, but one of them was
    fixed in 55fe48afb48e1dca0f179bb710b161a1abb1c6ee, 5 January 2008.)
    
    Fixes <https://savannah.gnu.org/bugs/index.php?59285>.
