Hi Ron. Remember that as defined, anywhere in the building is considered to be a means of egress, so all doors apply to your stated code provision.
Notice also a huge change in the 2003 edition of the IBC that is found in the last sentance of the first paragraph of 1008.1, which further validates the requirement by saying that if though the door isn't required (for egress width), it still must comply with the requirements of section 1008.
