ABNF for field-value

Hey all,
Section 3.2.2 of version 20 of the current draft, in the second 
paragraph, states:
 "The field value does not include any leading or
 trailing white space: ..."
so should the ABNF not be something like
field-value = (VCHAR / obs-text) [ *(field-content / obs-fold)
 (VCHAR / obs-text) ]
(ignoring the line break which may alter the semantic meaning)?
The current ABNF allows both leading and trailing whitespace, indeed 
would allow the whole value to be a space.
Since this definition would force the field-value to be non-empty, this 
approach would require allowing the field-value to be optional in the 
<header-field> element rather than requiring a, possibly empty, 
field-value. That approach makes more logical sense to me but might have 
repercussions of which I am unaware.
cheers,
 Adrian
