Details:

I just noticed that csv2cell does not work with paths containing a tilde
character. With a file '~/temp/test.csv' written by csvwrite() I get an error
if I pass the path containing a tilde to csv2cell:

>> csv2cell("~/temp/test.csv")
error: csv2cell: cannot open file ~/temp/test.csv for reading


... but not if I expand the tilde first:

>> csv2cell(tilde_expand("~/temp/test.csv"))
ans =
{
  [1,1] =  0.51339
  [2,1] =  0.23518
  [1,2] =  0.61376
  [2,2] =  0.60752
}


I am using Octave 4.2.1 with io 2.4.8. Installation of newer versions of io
fails ("csvexplode.cc:41:17: error: ‘const class octave_value’ has no
member named ‘OV_ISCELL’ [...]"). I can file a separate bug about this if
the behaviour is not expected in the transition to a new Octave release.
