typo in docs for set xtics

[Georg B. <g.b...@gm...>]

I found this in 4.2.3, but it seems to be in the CVS version
of gnuplot.doc too:

{ formt "formatstring" } should be { format "formatstring" }.

Thanks for making gnuplot such a powerful tool,
Georg

Thus spake the Lord: Thou shalt indent with four spaces. No more, no less.
Four shall be the number of spaces thou shalt indent, and the number of thy
indenting shall be four. Eight shalt thou not indent, nor either indent thou
two, excepting that thou then proceed to four. Tabs are right out.
