Gould (p. 105) says: "It is neatest ifa  hairpin that terminates at the 
beginning of a bar stops short of the barline, since the space between 
the barline and the subsequent first beat has no time value (bars 1-3). 
However, it is helpful to extend a hairpint to a first beat that is some 
distance after a barline, to show continuity (bars 4-6).

The example given matches LilyPon's output of the following file:

\paper {
  ragged-last = ##f
}

\relative {
  \time 2/4
  a' \< e'
  e, \f \> c
  g'2 \p
  \override Hairpin.to-barline = ##f
   f4 \< bes
  \time 3/4
 <gis b>2
  \f \> c,4
  \time 2/4
  es2 \p
}

which seems correct to me. The first three bars' default behaviour 
matches the description, and the - optional - result of the remaining 
three bars is achieved by overriding the default.
