The function shows the line number of the first error/warning that appears in the current buffer. If there are 20 warnings and the first warning exists on line 33, then vim-airline would show "W:20(L33)".
One can change how the line number is represented using: `g:airline#extensions#ale#open_lnum_symbol` and `airline#extensions#ale#close_lnum_symbol`
commit 232b641 did unfortunately disable tagbar completely, since
exists("*func") does not autoload the function.
So this time, try explicitly calling the function once, and if it does
not exists, it should be disabled and not cause any further errors.
closes#1555
rename g:airline#init#async variable to g:airline#init#vim_async
because that is what it is for: showing whether vim supports async. Is
not set vor nvim, because nvim always supports jobs.
When using vim-gitgutter and fugitive:
The hunks extension and the branch extension work as expected when the
file is first loaded; both parts are added to the statusline.
Once the cursor is moved and stopped for &updatetime ms:
1. The branch extension clears b:airline_head on CursorHold
2. Somehow (?) airline#statusline gets called on CursorHold
3. The hunks extension returns '' when b:airline_head is empty, causing
the hunks to be removed from the statusline.
It doesn't make sense to clear airline_head just because the cursor
moved, and the commit message adding the line doesn't say why:
13297cee03
Commit 174b7e1962 relies on airline_head
being set.
