I'll just say "+1", because that's what I meant.

Blame university for mathematical pickiness:

>> Tabs are 8 characters, and thus indentations are also 8

is wrong ;-) --

* Tabs _are_ 1 character (use a hex editor and see) and
* Tabs _are not always displayed_ as "8 characters"
[there exists a user for which \t != 8] [not me though]
* Tabs _are displayed_ as _much characters as the user specifies_.

(CodingStyle could need a clarification.)
