QDir: When using entryList() with a name filter such as "[" then it will fail to find any files with [ in it. The reason for this is that although [ is a valid character name on *nix in a file it is using the Wildcard pattern syntax in QRegExp. It should be possible to escape these characters in the name filter so that they can be used. To enable this, the pattern syntax for QRegExp should be changed to WildcardUnix.
