STYLE: Remove trailing whitespace in Fortran files

This is mostly a long term maintenance improvement.

Many coding styles require elimination of trailing whitespace, and
many editors and source code management configurations automatically
gobble up whitespace. When these tools gobble up whitespace, it
complicates reviewing the meaningful code changes.

By removing whitespace on one patch, it makes future
code reviews much easier.

  TEMPMAKER=tempfile

  echo "stripping $1"
  sed 's/[ \t]*$//' "$1" > $MYTEMP
