Hans,
the sample below hyphenates right what comes before \TexC in the
paragraph. Also the contents of \TexC are hyphenated right.
But hyphen is removed from standard text after the last \TexC command in
the paragraph.
I have just accidentally discovered it.
Fixed, thanks for noticing, it had to do with picking up the right 
settings after a change in alternative (we operate on several axis: 
language, glyph and hyphenation properties).

Many thanks for your help,
Pablo
