The denite extension functions return the content of some buffer-local
variables. Those variables are not defined, the first time the they are
accessed and therefore, the statusline is not updated later when
g:airline_skip_empty_sections is set.
So disable this variable in this window, by setting the
w:airline_skip_empty_section=0 variable in the denite window.

This is no explicit problem in Vim, however Neovim diverged in this
behaviour from Vim and requires the dict attribute to be present before
accessing the self attribute.
See neovim/neovim#5763
commit #3d667c32d3ac04 fixed a bug, that a section was not considered
empty for the statusline, also g:airline_skip_empty was set.
However unfortunately, this lead to a regression, makeing the tabline
ugly, because sections, that contained a single highlighting group would
be considered empty and would therefore be skipped. Since this is not
what is expected, make s:section_is_empty() return zero, when it notices
we are looking at a tabline.
fixes#1273
airline_c (which contains the filename) usually is used together with
the buffer number, so that several windows showing the a different
buffer do not share the same highlighting group.
This was fixed in 73aea86a, but unfortunately it was forgotten to not
only add this to the current group, but also modify the previous group
accordingly. This is what this patch does.
fixes#1268
consider a window with these splits:
,----
| file1
| ---
| file2
| ---
| file1
`----
If the top buffer is the active one and you start modifying this buffer,
this will also reset the highlighting for the inactive buffer2, since
the highlighting group 'airline_c_inactive' is used for both windows
(one having the unmodified buffer 'file2' and one having the modified
'file1').
This lead to the incorrect highlighting of the buffer name of file2.
Airline basically already created different airline_c<bufnr>_inactive
highlighting groups, but unfortunately did not use them.
Therefore, make the builder aware of this and always append the buffer
number to the group 'airline_c' if it is in an inactive window.
2) we need to make sure, the highlighting won't get overwritten, so
make the highlighter aware of this situation as well, by appending the
buffer number to the group name, if it creates the 'inactive' mode
groups and a buffer number has been given.
this fixes#1233
This is a little bit a hack, because by the time the separators are
added, it is not clear, if the following section is empty, therefore
we need to parse the content of the following section and eval the
expressions to find out, if this is empty
Remarks:
- catch all exceptions when eval'ing statusline
- make sure, that the seperators are highlighted
even when skipping empty regions (highlight group
names need to be adjusted)
- if a section is defined as empty, it will be removed completly from
the statusline. This means, it won't be called on the next update
and may not refresh properly (e.g. when the whitespace check
triggers, therefore, the whitesapce extension has to call an
explicit redraw whenever it is supposed to be refreshed)
