Should function and class docstrings mirror the Eigen documentation?

[Lucas-Haubert]

Yet, some commentaries / descriptions of the functions / classes are not strictly equivalent to the ones in the Eigen source code.
Should we make a perfect mirror of this documentation ?

One example, in eigen/decompositions.LDLT.hpp:

.def("matrixL", &matrixL, bp::arg("self"),
             "Returns the lower triangular matrix L.")

but in source code:

Returns a view of the lower triangular matrix L.
