[forge] multiples private strsplit.m

[Marco Atzeri]

Hi,
running tests for most forge package m-files, that I am packaging
for cygwin, I noticed that there are some old copy of strsplit.m around

/usr/share/octave/packages/cgi-0.1.0/@cgi/private/strsplit.m
/usr/share/octave/packages/dataframe-1.1.0/@dataframe/private/strsplit.m
/usr/share/octave/packages/miscellaneous-1.2.1/private/strsplit.m

that have at least a problem in the test area

+ pkg ('load', 'cgi')
+ test ('/usr/share/octave/packages/cgi-0.1.0/@cgi/private/strsplit.m')
***** assert (strsplit ("road to^hell", " ^"), {"road", "to", "hell"})
!!!!! test failed
ASSERT errors for:  assert (strsplit ("road to^hell", " ^"),{"road", 
"to", "hell"})

  Location  |  Observed  |  Expected  |  Reason
     .          O(1x1)       E(1x3)      Dimensions don't match
+ pkg ('unload', 'all')
+ endscript;

Questions:
- any specific reason to maintain this private function in the
  packages ?
  If I understood correctly private functions are only used if
  octave itself do not provide them.

- it was ever used the form
     strsplit ("road to^hell", " ^")

  instead of
     strsplit ("road to^hell", {" ","^"})

  for what I see the three package do not use it.

Marco
