raw2ascii looped while reading the dem30 header file

Dear TerraGear guru,

On my plateforme (Linux 2.6.15-27-amd64-generic with Ubuntu Dapper) 
raw2ascii enter a loop while reading the dem30 header file.

Whithout understanding any C++ character handling, I just modified an 
easy while condition in 
TerraGear-0.0/source/src/Prep/DemRaw2ascii/rawdem.c and it worked fine.

Here, rawReadDemHdr returned i = 1 after the last consistant line.

Following is a patch for it.


Cheers,

Alexis
