Because docs building is so complicated that it's quite hairy to write
makefiles, so that all portions of the docs that changed since last
build are actually rebuilt.  I experienced that the best way testing
changes in doc building is cleaning all output and rebuilding from
scratch, although I'm generally not interested in rebuilding snippets.

In topdir/out/lybook-db, it's not possible to make a difference between
what was created by web or test make targets.  However, I made web-clean
and test-clean erase topdir/out/lybook-db, which seems to be what most
people building Lily expect.
