This is the first of a couple of commits whose goal is to fix issues
with Cursor and MatchParen highlights. In particular, we strive to find
combinations that are pleasant and permit to distinguish matched
parentheses easily. More about this in the next commit.
In light themes, when cursorline is on and bold fonts are not used,
MatchParen highlighting is not visible. This commit solves the problem
by setting the foreground color to red, as in the original Solarized.
Fixes https://github.com/lifepillar/vim-solarized8/issues/15.
Problem: MatchParen highlighting in light themes inverts colors of
bracket, makes it look like cursor has jumped to matching bracket.
Solution: keep the parenthesis's foreground color when highlighted, and
make the background slightly darker instead of grey.
Fixes https://github.com/lifepillar/vim-solarized8/issues/11.
For all schemes other than the flat one, when g:solarized_contrast is
not low, use the same colors as the original Solarized for the status
line, with the exception of the dark high-contrast scheme, where the
colors of StatusLine have been darkened a bit to make them compatible
with WildMenu.
