    _______________________________________________________

Details:

In the current stable octave version, the mex c-api function mexErrMsgTxt("")
does not return control to the command prompt, as it should if an empty
zero-terminated string "" is passed as argument.

This differs from Matlab's behaviour, where the same call aborts the mex file,
printing an empty error message.

The original bug report #39271 was closed because the same behaviour for the
error('') function is consistent with Matlab's behaviour. However, this is not
true for the mex api.

The problem is easy to work around in my code, and therefore not really
important to me, but i thought i'll file a bug report anyway to the benefit of
other toolkits porting to octave.

Thanks,
-mario
