| Subject: findstr() handles empty string incorrectly
| 
| Bug report for Octave 2.1.30 configured for %OCTAVE_CONF_CANONICAL_HOST_TYPE%
| 
| Description:
| -----------
| 
|   When using findstr() on an empty string the vector [ 1, 2] is returned.
| 	IMO, an empty vector should be returned.
| 
| 
| Repeat-By:
| ---------
| 
|     findstr( "", "d")
| 
| Fix:
| ---
| 
|   diff below.  findstr.m is my fix, scripts/strings/findstr.m is
| 	the original

|     -               # Check for empty string
|     -               if( l_t < 1)
|     -                       v = [];

|          ind = 1 : l_t;
|          limit = length (s) - l_t + 1;
|          v  = zeros (1, limit);

Sorry for the long delay.

I made this change in the CVS sources.

Thanks,
