How to show the current filename in each split window's status line in Vim?

Question

I have a global statusline set, but it would be useful if each split window had the current filename in its own statusline.

Answer 1

OK, the default setting is empty so I added the following setting for stock console vim that seems to play nice with the NERDTree and Syntastic plugins:

" [buffer number] followed by filename:
set statusline=[%n]\ %t
" for Syntastic messages:
set statusline+=%#warningmsg#
set statusline+=%{SyntasticStatuslineFlag()}
set statusline+=%*
" show line#:column# on the right hand side
set statusline+=%=%l:%c
