Here's a version of dired-do-touch which operates on the selected
files in the same manner as the other Dired uppercase operations.
This version uses set-file-times, a primitive interface to
set_file_times, to touch the files.
The set-file-times primitive uses lisp_time_argument to get or parse
the time. This requires the change to editfns.c to provide
lisp_time_argument externally.
Making this change will require the set-file-times file name handler
to be added to the list of handlers in the Elisp reference.
