I think the intention is that we shouldn't insert those text fields
twice.  See the removed code in commit 36b9973dec65 and also
`image-dired-cmd-pngcrush-options'.

Perhaps we could make this unconditional, but then what should we do
about `image-dired-cmd-pngcrush-options'?  Should the options be removed
from there?
