[Wikipedia-l] "N"-mark on new articles on Recent Changes

[Jens Frank]

Hello,

at 19:04 server time  206.148.76.193 created a new article
Arnold Schoenberg. On Recent Changes it was marked with
a bold N as a new article.

Since the article had no markup, I edited it and saved it.
(19:12 server time). On Recent Changes, there is no "N"
anymore in front of the 19:04 change. On special:New_Pages
Arnold Schoenberg is not listed any more as a new article.

Is this a Bug or intended behaviour?

Regards,
