Re: Coding system of compressed PO files is not recognized

[Richard Stallman]

    I don't understand how that solve the problem.  When
    find-operation-coding-system is called, even if a buffer is
    given, the major mode of the buffer is not yet decided.

I am somewhat confused.  My understanding is that it recognizes the
coding system for a PO file by calling a function that is special for
PO files only.  Is that correct?

Can find-operation-coding-system tell, given the buffer, that the file
is a PO file?  I presume so.  What kind of test would you want to use?
