gnuplot doesn't doesn't really do that in the case of the default format 
"% g", either.  The Standard C functions of the *printf() family do it 
all by themselves, because they remove trailing zeroes in %g mode.

The real difference is between the %f and %g formats of printf():

	set ytics nomirror ; set y2tics
	set format y '% g'
	set format x '% f'
	set format y2 '% t'
	plot [1.01:1.08]  x, x axes x1y2

It might be possible to implement %t by use of %f instead of %g, but I 
wouldn't like to have to guarantee that there are no offensive consequences.
