Another "low-hanging fruit" although I don't think a ticket was made for
this was the issue I raised a few weeks ago regarding numpy.loadtxt().
Quick summary: if someone has been using np.loadtxt for reading multi-line
and multi-column text files (thereby getting a 2-D array), and then when
they encounter a single-line multi-column file, they get a 1-D array due to
the squeeze() function.  Also, zero-length files throw exceptions (but I am
not completely worried about this right now).

While this isn't an easy thing to fix without breaking compatibility, I
still think that adding a keyword "mindims" to specify the minimum number of
dimensions to return would 1) address the issue at hand, and 2) raise
awareness of the issue among users by having documentation for the mindims
keyword.  To maintain backwards compatibility, we can set it to zero by
default.

Just my 2 cents.
