No, that kind of fuzzy-logic behavior is very hard to follow if you're
writing a script and handling error behavior. What if you have both
foo.fits and foo.fits as filenames, and both have extensions? How
do you tell which you got, if you weren't sure you had both? You'd
have to have a relatively complex status variable that knew and
reported all the possible combinations, and you'd have to check it and
process all the possible errors. Yuk.
