"minimum-length" is applied not the real length of the hairpin, but to
the length of the hairpin **if it would not have been shortened by the
presence of a dynamic**.  IMHO it should apply to the _real length_ of
the hairpin (the printed one!), even if it is a "shortened hairpin"
(hey, it is usually these "shortened hairpins" that we —the users— want
to lengthen when we  \override Hairpin #'minimum-length !!).

It is not easy to explain this, I hope the following code will help you
to understand better what I mean.

%%%% Snippet

\version "2.15.24"

\relative c' {
 c1\< |
 c\mf |
 \override Hairpin #'minimum-length = #8
 c\> |
 % this "shortened" (due to the presence of the DynamicText) hairpin
 % does not have a _real_ minimum-length of #8 !
 c1\ppp\<^"too short!" |
 \override Hairpin #'minimum-length = #12
 c\fff\> |
 c\> |
 \revert Hairpin #'minimum-length
 c\mf\> |
 c\p
}
