I think it is a very bad idea to have hard tab characters in sources, since
it can lead to bogus differences between files (unless you have canonical
rules requiring maximal tabs). In GNAT we forbid tabs or trailing spaces (same
ind of consideration) in Ada sources.
But I think that random tabs in gcc C sources is well established. I know
that when I tried to argue for the no tabs rule in the GNAT C sources Richard
Kenner argued strongly against this.
