Details:

If I run some command that dumps a lot of text to the pager, hitting cntrl-C
doesn't immediately break.  So, continue hitting cntrl-C and the following
happens:


octave:1> y = 1:10000000
[takes a moment then pager starts scrolling]
 Columns 57086 through 57092:

      57086      57087      57088      57089      57090      57091     
57092^Cfatal: caught signal Interrupt -- stopping myself...
attempting to save variables to 'octave-workspace'...
save to 'octave-workspace' complete
octave:1> ^Coctave:1> 
octave:1> 
octave:1> z = 1
octave:2> 
octave:2> who
octave:3> 


It appears the line counter is advancing as normal.  Maybe it is just the
pager output that is broken at this point.  Is hitting cntrl-C supposed to
result in a fatal error?  Or just break out of the pager?
