    All commands processing file wildcards
    --------------------------------------
    It would be useful to allow multiple file exclusion lists, e.g.:

    dir/[!descript.ion]/a:/p/[! *.xxx *.yyy]

    The primary use would be during alias expansion, e.g.:

    alias dr=`*dir/[!descript.ion]/a:/p`
    dr /[! *.xxx *.yyy]

    In fact, allowing just one exclusion list in an alias and an additional one
    when the alias is expanded would by itself be a great help.

    Ultimately, of course, one might want for each selection / exclusion type
    (name, date, size, etc.) a full set of logical operators to combine multiple
    ranges, e.g., to select files whose size is in any one of a specific set of
    ranges.

    PDIR enhancements
    -----------------
    It would be useful to be able to provide a range or list of ranges for each
    reporting field, as specified in the /(...) option, e.g.: /O-r2r4-r0 would
    make the field 2 the primary key in descending order, field 4 the secondary
    key in ascending order, and field 0 the tertiary key in descending order.
    This sorting order would require that sorting would be for all reported
    files across all paths, thus requiring either "insertion sort", or
    collecting all reports before sorting is started.

    It would be useful to allow selection (inclusion/exclusion) ranges based on
    reporting fields, e.g. /[F5 min,max] to report only if field 5 is within the
    min,max range, or /![F5 min,max] to exclude files if field 5 is within the
    min,max range.

    It would be useful to allow applying a report field width specification to
    file sizes. When one knows that the largest file in a report is less than
    1,000 bytes, it is unnecessary to dedicate 15 columns to 3 columns of
    information. Conformance with CMD.EXE is irrelevant in PDIR - it has no
    equivalent in CMD.EXE.
