OK, thank you for reply.  I guess, "What M6 does is what M6 does," and 
one just has to get used to it, and then (all too often, these days) 
figure out how to work around it somehow.  

In the present case, I add the label to the plot because that's what I 
want on the exported graphic, which goes in my files and may be used for 
publications, slides, reports, class notes.  I like to do this using 
Labeled because it's a convenient approach, easy to code, and effective.  
I can write a module with the plot parameters and label string as 
arguments, that generates the plot, then calls Labeled; and then call 
this module repeatedly to generate multiple plots that are graphically 
consistent.  

If M6's programmers, can generate the PDF to display the plot plus the 
label on my computer screen all together **in a single cell* (and also 
with the \n line feeds properly interpreted), seems like they could 
manage to Export that cell as a single PDF file.  Programming the Export 
function to include the label but as a quoted string seems just bizarre.  
[Is there _any_ other situation where M6 shows a normal text string on 
screen, but Exports it to PDF as a quoted string?]

I guess the workaround in this case is to correct the exported plots in 
an external graphics app -- and add this to the growing list of poorly 
considered user interface decisions in M6.

[And by the way, AFAIK PlotLabel can't put a label anywhere except top 
center, and modifies the size of the plot itself depending on the label; 
and Plain TeX, which I use, has no \caption{}.]
