Oh, oops -- that's my fault; I edited the error message quoted in an old 
post, rather than actually running it to generate a real message, and 
missed the blank columns when I was hand-counting.  The blanks would 
very definitely be counted in a real error message.  Thanks for catching 
that!

There is still an off-by-one error; we number the first column as 1 
rather than 0.  Given that there's a very strong tradition in Fortran of 
numbering columns starting with 1, and that off-by-one errors in column 
location are within the noise level of locating things (given that 
nearly all errors are several columns wide), I think it makes more sense 
overall to keep it the way it currently is.
