Indeed: typing 'something.tif' twice should not be necessary. But the 
following could theoretically make sense (in analogy to GNU sed's 
-i/--in-place switch (which creates a temporary file and later 
*overwrites* the original file):

gdalwarp -i something.tif -t_srs EPSG:XXXX

However, as one hardly get things right in the first run: there is a 
good chance that the result is not what you want -- and the original 
file is gone :-(. At least this happens to me whenever I use sed's -i 
switch. So I wouldn't see a need for introducing this behaviour in GDAL 
command line utilitiies.
