irreversibly reversing range

[Mojca M. <moj...@gm...>]

Hello,

I accidentally used "plot [bigger:smaller]", but when I corrected the
mistake, the plotting range didn't restore to the appropriate value.
Would it make sense to fix that behaviour?

Example:

# ok
plot [0:10] sin(x)
# ok
plot [10:0] sin(x)
# wrong; plots as [10:0]; "set xrange restore" doesn't help; only "reset" does
plot [0:10] sin(x)

Thanks,
    Mojca
