Further problems with makeLSR

[Phil Holmes]

I've had another go at running makeLSR to update the snippet lists, and this 
time it seems to be reverting changes David made.  An example:

makeLSR runs convert-ly, and this seems to be replacing the 2.17.6 version 
number with 2.16.0 and reverting the change to the dot or hash syntax.  It 
looks as though convert-ly is not picking up the rule to update this syntax 
properly.  Anyone any idea why?
