Reparse an Rd object.
an Rd object
rdo to a temporary file and parses it
parse_Rd. This ensures that the Rd object is a "canonical"
one, since one and the same Rd file can be produced by different (but
equivalent) Rd objects.
Also, the functions in this package do not attend to attribute "srcref" (and do not use it) and reparsing takes care of this. (todo: check if athere is a problem if the tempfile disappears.)

(todo: why?) # (see also examples in Rdo_append_argument) Rdo_show(rdo2)
