Sync-to-go: src/pre-eqn..
Practically in sync.
This changeset includes fixes for [1] and [2].
(Quite honestly the fix for [2] (changing rounding from
"/\\n(.V+(\\n(.V/2)*\\n(.V\n" to "+(\\n(.V/2)/\\n(.V*\\n(.V\n" was
taken from GNU roff "as-is" without actual applying any own
intellectual property. I've verified that the bug existed already
in my 1.19.2 installation, however.)
TODO - The manual is *completely* useless and doesn't even document
TODO the basic eqn language!
TODO - neqn.sh.in: use -Tlocale or xxx (but: *not* fixated -Tascii)!
TODO I've not taken:
TODO - [
d40cf46] ([eqn] Add `delim on', 2013-01-06): really missing
TODO possibility to restore the former delimiters.
TODO - [
6360d7c] (Improve native Windows port., 2014-11-20,
TODO Eli Zaretskii). File names should be treated in a library.
