    _______________________________________________________

Details:

When I add directories to the search path using the "'-end'"-switch, addpath
shadows builtin functions without issuing a warning.

I'm on Ubuntu 15.10.


/tmp$ octave --no-gui --silent
>> addpath (genpath ('/tmp/ext'), '-end')
>> size
error: assert (false) failed
error: called from
    assert at line 92 column 11
    size at line 2 column 3
>> str2double
error: assert (false) failed
error: called from
    assert at line 92 column 11
    str2double at line 2 column 3
>>
/tmp$


The functions size and str2double in /tmp/ext only contain an assertion.

Since I have to deal with some projects containing their own versions of
essential functions (thanks Mathworks), I use the "'-end'"-switch to prevent
shadowing. If it can't be avoided, a warning would be great.

sincerely
