No, just that it was invented only recently (in Emacs terms).

Please do so.

Indeed, but I guess we should go with Emacs' conventions.  The question
then is, of course, if we should pro-actively convert our files.  One
strategy would be to convert one file after the other when one touches
it anyway, probably in a seperate commit.  At least we should try not to
have a file half tab-indented and the other part space-indented.
