That's 1.25 characters.  The printout from show key indicates 1 
characters.  The lack of consistency is

default                 value in character units
-------                 ------------------------
`samplen 4`    => 'sample length is 4 characters'
`spacing 1.25` => 'vertical spacing is 1 characters'

If the printout indicated 'vertical space is 1', i.e., unitless, then it 
could be a scale factor.  But then it would make sense that samplen 
should be a scale factor as well.
