The correct ISO 639 code for Pakistani/Western Panjabi seems to be 'lah', not 'pa'. We are keeping 'pa_pk.orth' for compatiblity with glibc. Signed-off-by: Behdad Esfahbod <behdad@behdad.org>
Previous Panjabi orthography was in the Gurmukhi script only, while in Pakistan, the Arabic script (called Shahmukhi) is used for Panjani.
