Sounds like a bug really. I mean, hunspell itself generally doesn't do
the parsing of text into words, the app gives each word to hunspell. And
we're *supposed* to be using the icu breakiterator to split words. I
suspect its a similar bug as this original one.

So... sure, file a bug, assign it to me (caolanm@redhat.com) and paste a
short two word example text into the bug and indicate where the word
break should be and I'll add a regression test for it and see if its a
trivial fix for Khmer too now that we're using the latest-and-greatest
icu.

That should at least be theoretically possible, albeit a bit tricky
seeing as the layout code is the bit that knows the width of the page
and does the line breaking, while the export filters don't get to know
that information. There was something similar done in the past IIRC to
pass around soft-page-break information so that export filters could
know where the layout last put the page breaks. I forget the details of
that though.
