;;;
;; * If NOSELECT is non-nil then just run `find-file-noselect' on each

;;;
;; * If NOSELECT is nil then calculate the `size' of the window for each file
;;;   by dividing the `window-height' by length of FILE-LIST.  Thus, `size' is
;;;   cognizant of the window-configuration.
;;;

  "Mark files for which PREDICATE returns non-nil.
With a prefix arg, unmark or unflag those files instead.

PREDICATE is a lisp expression that can refer to the following symbols:

    inode  [integer] the inode of the file (only for ls -i output)
    s      [integer] the size of the file for ls -s output
                     (usually in blocks or, with -k, in KByte)
    mode   [string]  file permission bits, e.g. \"-rw-r--r--\"
    nlink  [integer] number of links to file
    uid    [string]  owner
    gid    [string]  group  (If the gid is not displayed by ls,
                     this will still be set (to the same as uid))
    size   [integer] file size in bytes
    time   [string]  the time that ls displays, e.g. \"Feb 12 14:17\"
    name   [string]  the name of the file
    sym    [string]  if file is a symbolic link, the linked-to name, else \"\"

For example, use

        (equal 0 size)

to mark all zero length files.

There's an ambiguity when a single integer not followed by a unit
prefix precedes the file mode: It is then parsed as inode number
and not as block size (this always works for GNU coreutils ls).

Another limitation is that the uid field is needed for the
function to work correctly.  In particular, the field is not

refer at all to the underlying file system.  Contrast this with
`find-dired', which might be preferable for the task at hand."
