We could definitely add something like that, but is it specific to
f90-mode?  What about other Fortran modes?

Look at the index node you mentioned: what other menu item that
matches "read" there is more appropriate?  And what did you expect to
see instead?

The gfortran manual doesn't seem to describe the Fortran language,
only the GNU-specific extensions or something.  It lacks basic Fortran
keywords.  Perhaps that is the source of your confusion?
