Re: tabs v spaces in Emacs's source files

[Richard Stallman]

    Is there a convention on whether tabs or spaces should be used to
    indent Emacs's source files, or is it up to the maintainer of a given
    file? I don't want to propose one or the other, just ask if there's a
    standard.

You may as well always tabs, since they save space, and avoiding them
in any one file does no good.

Texinfo files are an exception; they are input for TeX so they should
not have tabs.  Texinfo mode takes care of that.
