I would like an indicator in my 'titlestring' that informs me if ANY changes
are present in ANY listed buffer. This would be more like a global indicator
for the 'modified' setting. What is the most efficient way to do this?
Currently, I've taken the naive approach:
function! g:ChangesExist()
let l:bufferList = filter(range(1, bufnr('$')), 'buflisted(v:val)')
for l:bufferNumber in l:bufferList
if getbufvar(l:bufferNumber, '&modified')
return 1
endif
endfor
return 0
endfunction
This seems like the most direct method, but I'm wondering if there's some
simple option or function call that I'm missing...
