I have an idea how to implement *intra*/word/ markup with minimal change 
of Org syntax. At first I had a hope that it is enough to introduce 
\relax entity that expands to empty string, but it does not work for 
second part of words: *intra*\relax{}/word/ is exported to
     <b>intra</b>/word/.
So it is necessary to support consuming spaces after such entity similar 
to TeX commands:
     *intra*\relax /word/
In Org "a\_      b" already behaves in the same way.

I do not like zero-width spaces since they are invisible, so they are 
not really "text" markup. Moreover, it is better to filter them out 
during export.

Another failed idea was to use export snippet or a macro for such purpose:
     #+macro sep $1
     *intra*{{{sep()}}}/word/, *intra*@@html:@@/word/

Important point that suggested solution works for all export backends. I 
do not consider explicit export snippets as a workaround since it 
requires code for all backends in org files.
