[PATCH 2/4] docproc: handle asciidoc templates

[Jonathan Corbet <corbet@lwn.net>]

There's really nothing different that needs to be done except for invoking
kernel-doc with the -asciidoc argument.  Look at the input file name to
recognize asciidoc templates, so no special command-line flags are needed.
