Sorry Andrey,

Stupid errors in test script, didn't actually run trim3 anyway, redone, and that 
and updated logs attached.

It appears the locale dependent [[:space:]] regexp no longer works but using 
escapes generated by echo still does, see corrected trim3, so perhaps use those 
for now, if you can, while I follow this upstream.

You may need to add escape sequences for any locale dependent spacing characters 
to the space string, so please let us know if there are.
