Fix for Issue #108 Entering a somethign in the 'Path field' triggers the `_path_changed` signal being triggered. This in turn calls Globals::localize_path(const String& p_path) with the currently entered string. localize_path then is replacing backslashes with slashes and calls afterwards `String::simplify_path` String::simplify_path is checking wheter a string starts with: - res:// - local:// - user:// If any of those is true it removes this section. However, if any of the first letters of those are matching begins_with returns true, which is wrong. It should only return true if the whole string is matched at the beginning. This caused the whole desaster and lead localize_path into an endless loop because out of `u` suddenly became user:// which it then tried again to localize and so on. This fix, fixes the root of the problem which is begins_with which should not return true if not the whole search string was matched. Signed-off-by: Vinzenz Feenstra <evilissimo@gmail.com>
