indexed tif images do not display

[Dan Greve]

I can never get relative paths in gdaltindex to work with mapserver.  I 
attached a program I use to change the gdaltindex shapefile based on a 
simple pattern.  Remove 'n' characters with pattern 'p'.

i.e. if all the records are /USA_Tiffs/something.tif

I do

gdaltirepath.exe -p f:/ -c 1 index.shp

will change all "location" (by default)  records to

f:/USA_Tiffs/something.tif

I find it's quicker than rebuilding the entire shapefile using gdaltindex 
which must open every file to be indexed. The -tileindex options permits 
fields of other than 'location'
