Actually, this behavior is discouraged (at least by me).  In reality
there's NO completely reliable way to automatically determine what
source files you want to build: there could always be backup files or
test files or other temporary files that happen to match whatever
pattern you come up with.

In my book, a build system that is not completely reliable is very, very

Whenever I'm asked about this I _always_ say, just list the files you
want to build explicitly in your makefile, or somewhere.  It's not
onerous to keep this list up to date (how often are brand new files
added, anyway?) and it saves a lot of headache and hassle.

However, obviously YMMV.
