Section 3.4.2 says:
o Delete all WSP characters at the end of each unfolded header field value.
It should say:
o Delete all WSP characters just before the CRLF at the end of each unfolded header field value.
A prior step in this section suggests that header field values include the trailing CRLF. If that is the case, then a header field value can't end with WSP, which suggests that this step is incorrectly specified. The correction I give here restores the apparent intent of this step.
