--- Comment #4 from urbanjost at comcast dot net --- Wow. I cannot get a pizza delivered that fast. Thanks! I have -Wtabs set in my compiler script and the script I use for editing codes does a :retabs after turning off tabs in vim(1) and runs any file ending in a Fortran suffix through expand(1) if using any other editor; so I would totally vote for -Wtabs being the default but I know a lot of others who would definitely vote for tabs being allowed as part of the standard. In fact, the majority of Fortran users I know would prefer it being standard.
