Errm, you will notice I was refering to Opera there not FF.

Also point of 2 above was that it was NOT an svg but HTML and shows that 
display of filenames is not consistent. 1 and 3 differ because 3 is 
using "name". This was to show how it offered more control.

So ,no, this was nothing to do with FF and did not show different 
behaviour wrt svg depending on how the file was opened.

The whole point is that browsers seem to take different choices of what 
to do if there is no title defined. Getting more consistency would be 
one reason to define what we want in a coherent way that browsers can 
display consistently .

I think I am presenting a good case why this needs to be dealt with 
correctly, not ignored. You are free to see things differently , of course.

Please read what I wrote. I in nowhere suggested that the current 
argument for "output" should be used as the svg title. My point was that 
if you consider this to be a function of the file rather than the 
terminal (a possition that I have agreed makes sense) it should be dealt 
with at the time the output file is determined. This means it has to be 
in set output.

It was you who said you thought using terminal "name" was not good and 
objected to reopening the terminal to reset it. That makes some sense 
but the overhead of reopening does not seem prohibitive.

Going with you idea that this is out of place in set terminal  would 
mean a new option in set output , not using the value of output itself.

My objection is that it _almost certainly_ will not fit in the tab. 
Opera seems to give it 12 characters. There is little chance that a the 
plot -title will be that short , thus the text in tab , which is the 
primary focal point when switching between tabs is rendered of little 
use for gnuplot svg output.

The mod you just committed fixes this from my point of view (thanks) but 
you seem unhappy with it.

I was trying to find a more rigorous solution that would satisfy your 
more complicated usage.

If you are not interested in taking it any further I'll drop it. Current 
cvs fits my needs fine.
