valfendi currently outputs what you say (plus type-of-word annotations). If it 
had fa'o-detection, it would lex it as /la xidEkel rIrxe fa'o tIgri 
selinistIkalIte/ with everything from /tIgri/ on resolved as foreign text. 
But the words after /fa'o/ are in fact /tIgris elinistI kalIte/, and if there 
were a Greek parser which saw an instruction to call the Lojban parser and 
then resume when the Lojban was finished, it would lose those three words, 
since the Lojban lexer cannot detect {fa'o} until it has read the end of the 
piece. That is why I think that {fa'o} should must be always followed by a 
pause: not because the algorithm can't lex it otherwise (it does, as well as 
lex some other illegally-pronounced phrases such as /kybuladjAn/) but because 
not putting a pause forces the algorithm to process text after the {fa'o} 
before it can detect the {fa'o}.
