Show threads feature is not used if ps wide option is not enabled

[Sinan Nalkaya]

Hi,

I intended to use "Show Threads" feature in ps without -w option is enabled, but i couldn't.

Is there a specific reason for that?

This patch seems to be fixing the issue if there is no specific reason for that.
