More spurious <break/> problems in exports

More spurious <break/> problems in exports

List,

Another oddity with <break/> elements in XML / xhtml / html export:

With a defined highlight, a break is inserted if the highlight is the 
first item in an environment. If it is not the first item in the 
environment, no break is inserted.

Most of the other odd breaks can be dealt with in css. These are more 
difficult to tame -- for example, in the startlines environment in the 
example below, there is not enough information preserved to know if the 
tagged item is supposed to be a single line or not.

(Tests using 2018-07-17 beta on Win64.)

Has anyone dealt with this before? Is there a way to control the 
insertion of the breaks?

MWE:

    \setupbackend     [export=yes]
    \definehighlight  [emIt]
                       [style=italic]
    \starttext
    \startparagraph
       {\emIt Taa} aaaaaaaaaaa aa aaaaaaaaa aaaaaa aaa aaaaaaaa aa aaaaaaaaaa
       aaaaaa. Taa aaaaaaaa aaaaa, aaaaa aaaaaaaa aa aaaaa aaaa aaaaa.
    \stopparagraph
    \startparagraph
       Taa {\emIt aaaaaaaaaaa} aa aaaaaaaaa aaaaaa aaa aaaaaaaa aa aaaaaaaaaa
       aaaaaa. Taa aaaaaaaa aaaaa, aaaaa aaaaaaaa aa aaaaa aaaa aaaaa.
    \stopparagraph
    \startlines
       {\emIt Xyz} abcdefg
       Xyz {\emIt abcdefg}
    \stoplines
    \stoptext

You get this, with the numbers representing the paragraph number:

\starttext
% foo

\startparagraph
   \emIt{x 1} a 1
\stopparagraph

\startparagraph
   {\emIt x 2} a unset
\stopparagraph

\stoptext

of this:

\starttext
foo 1

\startparagraph
   \emIt{x 2} a 2
\stopparagraph

\startparagraph
   {\emIt x 3} a 1
\stopparagraph

\stoptext

so, when the par number is effectively set inside a group you end up 
with bad tags which will force that break because it's a different 
paragraph .. no way to intercept or chaneg that

The best I can do is issue a warning like

export > fuzzy paragraph: a (U+00061) [space] - (U+0002D) 2 (U+00032) 1 
(U+00031) 4 (U+00034) 7 (U+00037) 4 (U+00034) 8 (U+00038) 3 (U+00033) 6 
(U+00036) 4 (U+00034) 7 (U+00037)
backend         > x

so that one can fix the source.

Changing from a font switch ­– {\emIt text} – to a command – \emit{text} 
– resolves the issue for these cases. I will add a note to the wiki 
that, when changing from font switches to highlighting, one should 
change the syntax.
