Could not create file due to invalid name -- upgrade error in plugins

[Denis-de-Bernardy]

Ran into this when upgrading a site on yahoo hosting. Some hosts, apparently, forbid files to start with a dot or to contain spaces.

And sure enough, feedburner-feedsmith contains such a thing. Maybe we could highlight the issue in the plugin repository to ensure no files ever get added with a space in them?

Also, could Tony get in touch with the folks at Yahoo and make them aware of the issue? It's crippling.

I do not see the point in restricting what legal characters filenames can or cannot contain, If a plugin uses a file like that then notify the author directly, I dont think its WordPress/WordPress.org's job to tell plugin authors about web hosts oddities.

The only place it'd belong would be on the !Wordpress.org codex under notes on the hosting providers for WordPress installation..

Agreed, up to a point -- I still think someone over at Automattic should give a notice to Yahoo.
