All devs,

as discussed recently, we decided to replace tabs in our source code
with spaces and to remove trailing whitespace.

The CMP has been updated but is still being worked on.

I committed the source code changes today in commit f09e17c3c564.

*Please configure your editors* accordingly to keep this new standard
alive, i.e.:

- use 2 column indents
- use space for indenting
- do not use tabs for indenting
- do not use tabs for "trailing comments"
- etc. etc.
- avoid adding trailing whitespace
- remove trailing whitespace on exit if possible [1]


Note: A common issue is when adding an "empty line" in indented code
like the following. Some editors "indent" the "empty" line with spaces
up to the current indent level (column) - which would effectively add
trailing whitespace:

function a(int b) {
static int i;
i++;
<<< empty line: this is where whitespace gets added!
return b+1;
}

[1] Take care to do this only for source and other text files that don't
have significant trailing whitespace. Some shell scripts may have such
significant trailing whitespace!

Thanks in advance.
