 The fundamental problem is, really, that 1) unlimited number of
 results and 2) launching a pager MUST NOT be conflated in the single
 option.
 
 #1 - whether1 unlimited number of results should be the default (at
 least for the short format) - may be argued.
 
 #2 is absurd (especially so when enforced along with #1).  This is
 Unix.  We know how to pipe output to a pager, or some other program if
 need be.
