[pacman-dev] [PATCH 3/4] doc: use implicit rules to build manpages

[Dave Reisner]

Use implicit dependency rules to translate asciidoc inputs to HTML and
manpage outputs. We should only have to declare explicit dependencies
for odd cases, e.g. the PKGBUILD documentation has an additional include
file and isn't a 1:1 conversion.
