I don't get what's the use of adding an additional option whose effect will be visible only when certain attributes values is greater than 78 characters. If none of the attributes have value greater than 78 character , the output for both qstat -f and qstat -f1 will be same. To me -1 doesn't look very meaningful either, since attributes are already shown in new line.
I feel we should extend -f option to accept an optional argument like "pretty" or "wide" and keep one of them as default. Where option "pretty" will trim and add new line to values greater than 78, whereas option "wide" will not.
Adding an option like -1 gives an idea that it can be used with other existing option of qstat, which I don't think is intended in this requirement otherwise it should be added in the EDD.
eg. like what happens if user runs : qstat -1 job.id.
