 I'm experimenting with ways to detect themes & plugins WordPress can't
 upgrade automatically, and found that wp_get_themes() (wp-
 includes/theme.php) returns an empty array if one of the theme directories
 is unreadable (chmod 770, neither owner or group exist).

 Currently, the search_theme_directories() function returns false if any
 scandir() calls return false. Shouldn't it return a list of valid themes
 it ''can'' access, ignoring the ones it can't?

 The attached patch issues a "continue" statement if scandir() returns
 false, so at least some information is returned. It isn't enough to help
 me detect those cases where a theme can't be updated, but it's probably
 more useful for people who need a list of themes.
