Hi

this is kind of related to #833496.

The docbook2man command does exit with 0 even if it fails. This makes
debugging build failures quite tricky as you just notice missing file
later and not the failed command:

$ docbook2man man/colorhug-backlight.sgml 
Using catalogs: /etc/sgml/catalog
Using stylesheet: /usr/share/docbook-utils/docbook-utils.dsl#print
Working on:
/home/nijel/work/debian/colorhug-client/man/colorhug-backlight.sgml
/usr/share/docbook-utils/backends/man: 10:
/usr/share/docbook-utils/backends/man: nsgmls: not found
Done.
$ echo $?
0

Best regards
