[web2py] text field display when writable=False

[szimszon]

Is there a way to replace \n with <br /> and space with &#32; in the 
displayed value of text field if the field is writable=False and displayed 
in crud form:

db.define_table('some_table',
  Field('some_text','text',writable=False)
  )

crud.update(db.some_table,request.args(0))
