passing multiple arguments to open requires quotations

[HalosGhost]

If you try to use open (or tabopen) with multiple terms, only the first word (as delimited by whitespace) will be opened. In order to get around this, you must quote the complete argument.

However, to my knowledge, there is no benefit from passing multiple terms (e.g., it does not open all the results in different tabs), the extra terms are just lost—this signals to me that the default behavior should change so quotation is not necessary or so that multiple terms (either multiple, individually quoted entities or multiple non-quoted entities) would have some different behavior that obviated the need for quotation.
