Better error detection

Doesn't seem to be happening anymore. Can probably be closed. Sorry!

I had the same problem. It seems that it happends only when trying to create new pages. Solution is to make first letter of the title uppercase.

This problem occurs when M-x mediawiki-open-page-at-point at the link that have spaces around the ` | ', eg. [[Page about | page]]

Solution:
Remove spaces: [[Page about|page]]

I am getting this problem on our private Wiki even when the page name already exists and has no spaces.

No problem editing Wikipedia.

Using edebug, I've found that I do not have an edit token. I think I am not managing to log in correctly. This Wiki has a nonstandard authentication method that might have something to do with it.

pairs's value is
(("title" . "Sandbox")
 ("text" . "test\n\ntest 2")
 ("summary" . "x")
 ("token")
 ("basetimestamp" . "2010-10-19T22:46:05Z")
 ("starttimestamp" . "")
 ("format" . "xml")
 ("action" . "edit"))

I spent more time on this than I meant to, but I found that the reason I didn't have an edit token is because the site at x.example.com was trying to set a cookie on "example.com" instead of ".example.com" so I never authenticated properly. Then I found out that our Wiki doesn't support the edit action anyway.

thank you for the good bug reports. I'll at least try to improve the error reporting in the following cases:

* if you aren't setting a proper cookie/token
* if your your wiki doesn't support editing.
* If you try to create an illegal name.

Also trimming ending spaces -- it would help if mw.el did that automatically.
