    sys-file-reader: Don't warn if compression bias field is 0.
    
    Some software writes a value of 0 to the compression bias field.  We
    expect that this field has a value of 100 and warn if we see any other
    value, but there is no real need to do so (because it is very likely
    that we can read the file correctly in any case).  So suppress the
    warning if we see a value of 0 here, because it bothers users.
    
    Thanks to Tony Reardon <address@hidden> for reporting this
    unnecessary warning.

commit 399bf939cf7597e9dbe1810a07ffcb5c2ed57d32

    por-file-reader: Tolerate short lines when detecting portable files.
    
    When the portable file reader reads a file, it assumes that a line
    shorter than 80 bytes should actually be padded out on the right with
    spaces, because this is a fairly common problem in practice, perhaps
    due to text editors or other software that drops spaces at the end of
    a line.
    
    However, pfm_detect, the function that is supposed to detect whether
    a given file is an SPSS portable file, did not apply this heuristic to
    the data that it read at the beginning of the file, and thus files in
    which the first few lines were truncated this way were not detected
    properly as portable files.
    
    This commit fixes the problem by making pfm_detect a little bit
    smarter.  It would probably be better to actually unify the
    file-reading logic, instead of implementing it in two separate places,
    but this appears to work adequately too.
    
    Thanks to Tony Reardon <address@hidden> for reporting the problem
    and supplying a file that demonstrated it.
