Comment (by ncohen):

 Yo Dima ! If you happen to write a LP-related ticket, could you do that ?

 {{{
 #!diff
 +++ b/src/sage/numerical/mip.pyx
 @@ -1183,7 +1183,7 @@ cdef class MixedIntegerLinearProgram(SageObject):
              if b.is_variable_integer(i):
                  var_type = 'an integer'
              elif b.is_variable_binary(i):
 -                var_type = 'a boolean variable'
 +                var_type = 'a boolean'
              else:
                  var_type = 'a continuous'
              if varid_name[i] == str(self.gen(i)):
 }}}

 Otherwise we get stuff like that :

 {{{
 sage: p.show()
 Maximization:

 Constraints:
   x_0 <= 1.0
 Variables:
   x_0 is a boolean variable variable (min=0.0, max=1.0)
 }}}

 And it does not seem worth a ticket of its own...
