convert-ly.py in 2.25.7 "broken"

If I use Frescobaldi's "Update..." tool, files with version numbers less 
than 2.25.6 get updated to 2.25.6 and those already at 2.25.6 are not 
touched.

If I compare the convert-ly files in 2.25.5 and 2.25.6 I see they are 
almost identical except for version number.  That is not true, however, 
when comparing 2.25.7, starting from the first line!

(Win-64 build)

Thanks
