Subject: [eqn]: Fix Savannah #68115.

* src/preproc/eqn/eqn.am (neqn): `-f $(SH_DEPS_SED_SCRIPT)` should be
  placed before further `-e` substitutions so that it does not impact
  the later expressions.  This fixes the sed command to replace "@g@" in
  neqn.sh correctly.  The `/^$/N` in "shdeps.sed" (generated by Keith
  Marshall's "arch/misc/shdeps.sh") might be implicated.

Fixes <https://savannah.gnu.org/bugs/?68115>.  [Problem introduced by me
in commit 2b86c9332c, 4 February.  --GBR]
