My educated guess (standing in for my failing memory!) is that it is to
ensure that the space at the end of the line is not discarded as it is
'critical' to the correct interpretation of the string as a sig
delimitor.
>From RFC1341
MIME (Multipurpose Internet Mail Extensions): Mechanisms for Specifying
and Describing the Format of Internet Message Bodies
5.1 Quoted-Printable Content-Transfer-Encoding
Rule #3: (White Space): Octets with values of 9 and 32 MAY be
represented as ASCII TAB (HT) and SPACE characters, respectively, but
MUST NOT be so represented at the end of an encoded line. Any TAB (HT)
or SPACE characters on an encoded line MUST thus be followed on that
line by a printable character. In particular, an "=" at the end of an
encoded line, indicating a soft line break (see rule #5) may follow one
or more TAB (HT) or SPACE characters. It follows that an octet with
value 9 or 32 appearing at the end of an encoded line must be
represented according to Rule #1. This rule is necessary because some
MTAs (Message Transport Agents, programs which transport messages from
one user to another, or perform a part of such transfers) are known to
pad lines of text with SPACEs, and others are known to remove "white
space" characters from the end of a line. Therefore, when decoding a
Quoted-Printable body, any trailing white space on a line must be
deleted, as it will necessarily have been added by intermediate
transport agents.
