make gnuplot.tex fails due to PS_COMMON_OPTS1,2, PS_COMMON_DOC1,2

[Petr M. <mi...@ph...>]

Building
 	make gnuplot.tex    (.pdf, .dvi, .html)

in docs/ fails due to wrong positioning of macros PS_COMMON_OPTS1,2, 
PS_COMMON_DOC1,2 in allterm.h.

It seems epslatex.trm uses them before they are included via 
START_HELP(00psglobal). Could someone fix it?
