I'd guess the latter.  I'll CC: this to Steven G. Johnson, our
resident Fortran expert, to see what he thinks.

While we're in the neighborhood, I noticed some POSIX conformance
bugs in that area.  POSIX doesn't allow you to say things like this:

sed 's/\"//'

since \" has undefined behavior in a BRE (Basic Regular Expression).
Instead, any of the following will do:

sed 's/"//'
sed 's/["]//'

Personally I think the first is clearest....
