1) If you upload a big file that already exists, you don't get the warning
about overwriting, answering "Yes" to the size warning overwrites.
2) False "edit conflicts" when editing a section and edits are made to the
section heads. Actually this kind of makes sense, since there must be some
sort of "place marking" when only a section is edited. For example, edit
the last section and put a new section at the top of the edit, bumping the
original down. I didn't realized that I wasn't logged in when I did this,
and was only able to save my changes by:
* copying the changes
* abandoning the article
* logging in as sysop
* navigating to the article and pasting the changes into a fresh edit
(using v1.3.?)
