template_depends was adding a dependency on the source filename,
instead of on the page name when a template is a page. Such a
dependency doesn't work.
Since misctemplate is called with a page context, the comments plugin
thinks it should add that, as well as the comment link in the actionbar.
I kept the comment link because a quick link back to the comments to a page
is sorta useful.
This reverts commit 4cf185e781.
That commit broke t/po.t (probably the test case only is testing too
close the the old implementation and needs correcting).
Also, we have not decided how to want to represent it yet, so I'm not
ready for this change.

Cleanly fixed case where destdir file failed to be written because there
was a directory with the same name. This can be detected with no extra
system calls, and dealt with by finding all pages that wrote files
inside the directory, and removing them and the directory.
The other, inverse case would be expensive to detect in will_render,
since it would need to check each parent directory of the file to see
if the directory is really a conflicting file. But prep_writefile
already does a similar scan for symlinks in the path, so I added code
there to remove the conflicting file. This fix assumes that the file
is written using writefile, and not some other means (but using other means
would be a security hole too, so hopefully nothing does).
There are two sub-caces. If both source files still exist, the winner that
renders the destination file is undefined. If one source file is deleted
and the other added, in a refresh, the new file will take over the
destination file.
