(svn r4586) - Codechange: Recursive commands that rely on _error_message to handle success/failure can fail if a recursive call fails but doesn't set the error message, thus resulting in an old, possibly erroneous being used (see FS#130 prior to r4585). Now properly reset the global variable _error_message in these cases.
