Bug#845355: ZynAddSubFX : install upstream manpage rather than the (quite old) debian/ one

[trebmuh at tuxfamily.org]

Package: zynaddsubfx
Version: 3.0.0-1

Dear debian maintainers,

I saw there is an upstream manpage shipped within the sources :
https://github.com/zynaddsubfx/zynaddsubfx/blob/master/doc/zynaddsubfx.1.txt
which looks like (much) more updated than the debian/ one:
https://anonscm.debian.org/cgit/pkg-multimedia/zynaddsubfx.git/tree/debian/zynaddsubfx.1

Would that worth it to enjoy the 3.0.0 version for stretch to set it up 
for
installation?

Hope that helps,
Olivier
