[groff] 10/12: src/preproc/eqn/eqn.am: Simplify.

[G. Branden Robinson]

gbranden pushed a commit to branch master
in repository groff.

commit f432d98f0c3f16a1035e842d497e55c337a28852
Author: G. Branden Robinson <g.branden.robinson@gmail.com>

    src/preproc/eqn/eqn.am: Simplify.
    
    * src/preproc/eqn/eqn.am (neqn): Simplify: drop removal of target prior
      to overwriting it; any system we can build groff on should have a
      shell that implements the clobbering semantics of the POSIX shell '>'
      operator.  (If this isn't true, we have _many_ other target rules in
      our build to which we must add prefatory `$(RM)`s, or I miss my
      guess.)
    
    Also tweak legal notice formatting.
