commit eb58c6a6ba7f77c2c16016db064524df598ef421
Author: Jannis Pohlmann <[e-mail]>

    Fix bugs #3532 (umask < 0022 not honoured) and #5813 properly (I hope).
    
    The previous patch applied in e53de71e6add9b28ba034111a1d19db7def8f7e7
    made things worse than before: it used DEFFILEMODE which seems to be
    BSD-specific for creating files. It also reset the umask to 0 when
    creating the first directory with _thunar_vfs_io_jobs_mkdir().
    
    What we really want is to use 0777 (dirs) and 0666 (files) and let the
    standard C system calls like open() apply the umask value. This should
    work on all POSIX-compliant systems.
