g_rmsf group index instead of atom number in output
The behaviour of g_rmsf output is weird. When selecting an arbitrary group of atoms for rmsf calculation, the resulting rmsf.xvg file contains in the first column the indices of the chosen group elements starting from one and not (as expected) the atom number indices. In my opinion the user expects the atom number which he can compare to the .gro file e.g. and no relative indices which he has to recalculate with the .ndx file to absolute atom numbers.
I implemented a small patch to provide the desired behaviour even though I now, that this could break some scripts of users who came to terms with g_rmsf.
Any comments? Probably I have overseen some crucial detail to give meaning to this behaviour of g_rmsf?
