Accept_different_schemas missing from ogrtindex documentation

[Jukka Rahkonen]

The flag -accept_different_schemas that was added by #3141 is documented in the command line help

ogrtindex --help-general

However, the flag is not documented in ​http://www.gdal.org/ogrtindex.html.

Errors due to different schemata will be more common in GDAL 2.0 because of RFC 31 ​https://trac.osgeo.org/gdal/wiki/rfc31_ogr_64 at least with shapefiles because for example integer fields Number(9.0) and Number(10.0) are now considered as different types Integer and Long integer.

I found the command help from inside http://trac.osgeo.org/gdal/browser/trunk/gdal/apps/ogrtindex.cpp. There is

printf( "  -accept_different_schemas: by default ogrtindex checks that all layers inserted\n"
        "                             into the index have the same attribute schemas. If you\n"
        "                             specify this option, this test will be disabled. Be aware that\n"
        "                             resulting index may be incompatible with MapServer!\n" );

There is something wrong with the indentation and it would be good to remove some space characters, but what I like to edit is page ​http://www.gdal.org/ogrtindex.html. However, I do not know from where in the source code it comes.

The source for ​http://www.gdal.org/ogrtindex.html is apps/ogr_utilities.dox
