HACKING: Use space char for indentation.

Browse Source 
* HACKING.tex: Whitespace/indent section is probably out of date. Rephrase.
  Remove the editor recommendations, as I don't know what would be correct.

GNU coding standards apply. Indentation follows the result of
invoking GNU indent (as of 2.2.8a) with no arguments. Note that this
uses tabs instead of spaces where possible for leading whitespace, and
assumes that tabs are every 8 columns. Do not attempt to redefine the
location of tab stops. Note also that some indentation does not
follow GNU style. This is a historical accident, and we generally
only clean up whitespace when code is unmaintainable due to whitespace
issues, to minimise merging conflicts.
invoking GNU indent (as of 2.2.8a) with the --nut argument.
For GNU emacs, use indentation style ``gnu''.
For Vim, use the following lines (note that tabs are at 8, and that
softtabstop sets the indentation level):
set tabstop=8
set softtabstop=2
set shiftwidth=2
set noexpandtab
Originally, tabs were used instead of spaces, with tabs are every 8 columns.
However, tab's interoperability issues mean space characters are now preferred for
new changes. We generally only clean up whitespace when code is unmaintainable
due to whitespace issues, to minimise merging conflicts.
Be particularly careful not to break platforms/protocols that you
cannot test.
