This is an experimental feature that allows to display the statusline in
the tabline. It might still be a bit rough, but seems to work so far.
Remaining problem:
- Mode changes are not immediately detected, only after moving the
cursor
fixes#1388closes#1867
This was used as a workaround to fix a highlighting bug, which was fixed
in Vim 7.4.1511 and therefore, we need to correctly detect that the
patch was applied and in that case skip adding those extra groups.
As a bonus, when not using those empty %( %) groups, the
skip_empty_section test will correctly handle this and therefore this
closes#1351
1) Make sure airline_error and airline_warning highlighting are
different, so that the correct separator will be drawn. This
fixes#982.
2) allow to deactivate %(%) to workaround a vim bug, that may cause
leaking of colors from one section to the next and adding additional
spaces. This needs to be fixed upstream:

Possibly, also related to neovim/neovim#4147
Use `:let airline#extensions#default#section_use_groupitems = 0`
to disable grouping of statusline items
