offset error

[Tait <gnu...@t4...>]

This works:
plot 'gpdata1.txt', '' using 1:2:("x") with labels offset 3, ''

... but this doesn't:
plot 'gpdata1.txt', '' using 1:2:("x") with labels offset 3, '' with linespoints

... and this does:
plot 'gpdata1.txt', '' using 1:2:("x") with labels, '' with linespoints

The error is "duplicated or contradicting arguments in plot
options" with the arrow pointing to the last "with". It appears
to be some kind of error with offset.
