[PATCH 3/5] Silence xsltproc when writing manpages

[Jon Turney]

Unless make is invoked with V=1, have xmlto pass the parameter
'man.output.quietly=1' to xsltproc to suppress "Note: Writing foo.N"
output from the manpages stylesheet.

(This doesn't quite do what it says: The output is not silenced if V has
any value, including 0.  You could consider that either a bug or a
feature.)
