If everybody could use his own interpretation of how width tabs are shown the 
maximum column restriction gets pointless.

historical like the 80 columns from the vt100 and such terminals

of course I meant without the function part; no idea why I wrote it there.

good point

I have setup a wiki page: 
http://wiki.archlinux.org/index.php/DeveloperWiki:Bash_Coding_Style

And yes, this should just for bash and should appy to all our scripts 
including init scripts etc.. For PKGBUILD we might want to add some more 
specific extensions to this (I suggest a separate page for these)
