Hi,
I've seen that in simple.el indentation is inconsistent, sometimes using
spaces only and sometimes tabs and spaces. Some files seem to have more
consistent indenting using tabs and spaces, though some other files use
only spaces.
I thought that the convention was to use the tabs + spaces style, was I
wrong? I'm pretty sure this is documented somewhere, but I couldn't
find it.
Cheers,
Nico

From .dir-locals.el:
(emacs-lisp-mode . ((indent-tabs-mode . nil)
(electric-quote-comment . nil)
(electric-quote-string . nil)))
(I couldn't find this documented either).

I think the general understanding is that there is no consistent pattern
of spaces vs. tabs+spaces in effect, and that this is not an important
thing.
Way back in history, tabs+spaces was, I believe, universal, since it
saved on characters when the amount of RAM and disk space were a minute
fraction of today's.
I would ask, however, that a systematic attempt to convert to a
consistent spaces only is NOT made. This fouls up diffs, giving the
impression of change where there is none.

We only fix whitespace when making some real changes, that's why you
see inconsistent use of TABs in some Lisp files.

This is valid for files edited in the Emacs source tree. If they are
merged from somewhere else, like the Tramp files, this doesn't apply.
