Master, Default or none for brand new "po" file for the language

[Edmon Begoli]

I am going to create a currently non-existing translation of python-meh file.

There is no version in Bosnian so I am creating a file from master *.pot.

How should I name this file if the original is named:

python-meh.master.python-meh.pot

I was planning to name it:

python-meh.master.python-meh.ba.po

Should I name it:
python-meh.ba.po

?

Thank you,
Edmon
