Actually, that depends on what comint-dynamic-complete-as-filename was
used for: if it was used as a *command*, then
comint-dynamic-complete-filename is a good replacement.  But if it was
used within something like comint-dynamic-complete-functions, then the
better replacement is comint-filename-completion.

IOW, in the case of idlw-shell.el, the better replacement is indeed
comint-filename-completion, tho it requires changes in
idlwave-shell-complete (basically making it an alias to
completion-at-point and turning its body into a list of functions to put
on completion-at-point-functions).
