Section 3.1 says:

user-pass-char = B-CHAR

NOTE: a server implementation MAY parse AUTHINFO USER and AUTHINFO
PASS specially so as to allow white space to be used within the
username or password.  Such implementations accept the additional
syntax (making these two items inconsistent with "token" in Section
9.8 of [NNTP]):

user-pass-char =/ SP / TAB

It should say:

user-pass-char = CTRL / %x21-FF

NOTE: a server implementation MAY parse AUTHINFO USER and AUTHINFO
PASS specially so as to allow white space to be used within the
username or password.  Such implementations accept the additional
syntax (making these two items inconsistent with "token" in Section
9.8 of [NNTP]):

user-pass-char =/ SP / TAB

Notes:

RFC 3977 defines B-CHAR in section 9.8 as:

B-CHAR = CTRL / TAB / SP / %x21-FF

It already contains TAB (%x09) and SP (%x20). Therefore, we have
to define user-pass-char as any byte character except NUL, TAB, LF, CR
and SP. Otherwise, the note does not make sense.
