 The documentation on array indexing
 (http://docs.scipy.org/doc/numpy-1.6.0/reference/arrays.indexing.html#)
 contains a few details that look strange to me, that I list here in their
 order of appearance in the text:

 1 - "In order to remain backward compatible with a common usage in
 Numeric, basic slicing is also initiated if the selection object is any
 sequence (such as a list) containing (…)". Wouldn't it be more correct to
 write "any *non-ndarray* sequence (such as a list)…"?

 2 - About negative indexes: "if i < 0, it means n_i+i": I guess the
 correct value is "d_i+i" (d_i is the size of the i-th dimension, in this
 part of the text).

 3 - About the first slice number i: "Then, if i is not given it defaults
 to 0 for k > 0 and n for k < 0 ." I guess the correct value is n-1 (= last
 element), for k<0, no?
