Often (e.g. for Python) Error is used to indicate
whitespace mistakes (e.g. too much whitespace).
Since in Solarized 8 Error does not have any
background colour, these errors are not visible
(@fladd).
Fixes https://github.com/lifepillar/vim-solarized8/issues/63.
This sets a "flat" status line, vert bar and tab bar in all variants.
It does not have any effect for solarized8_flat, because "normal" and
"flat" are effectively the same in that case.
The separator makes it clear how a window has been split, which is
useful, for example, when you rotate windows (<c-w><c-r>). The separator
may be suppressed by the user with 'fillchars'.

Merge dark and light variants together. Now, you must select the
background color before loading the colorscheme, e.g.:
se background=dark
colorscheme solarized8
