gd.trm and multiple plots with png

[Jim K. <je...@kl...>]

Would it make any sense to hack gd.trm to
add an option to detect when a new plot is
created and if output is to a non-pipe named
file to auto-append a number ahead of the extension
and close/reopen the file?  Quick inspection
of the code suggests that it can be done but perhaps
there are gotchas and/or complexities that don't
show on the surface.  For multiplot plots as
an example.

An option named, say, auto_number_files ?

Issuing "set output" commands for every plot
can be a tedious retrofit to something that
works with PS or PDF.

Comments?
