[Octave-bug-tracker] [bug #52647] missing function: erase (introduced Matlab 2016b)

[Sahil Yadav]

Follow-up Comment #19, bug #52647 (project octave):

If somehow, we are not able to address the case highlighted by Doug, we can
switch to this version (due thanks to Andy and Doug) of ours which is slightly
more faster than this <https://savannah.gnu.org/bugs/?52647#comment11>
version. 

But there's a problem with this. Test cases on lines 173,175, the erase
function returns sq_string of size 0x0 and we expect it to be null_sq_string
('') . Also, one of the test cases written by Rik is wrong according to me 


%!assert (erase ("Hello World!", {"o"; "World"; " "}), "Hell!")  


The expected string should be "HellWrld!" instead.
All other considerations pointed by Rik in coding style have been included in
this code (using STR and MATCH instead of STR1 and STR2 resp.)
