This is not an actual pull-request but rather an RFC (request for comments) from
the KTextEditor, Kate and KDevelop developers, because I failed to solicit any
feedback on the kdevelop-devel@ and kwrite-devel@ mailing lists.
While trying to make an exact port of Solarized to Kate/KDevelop (more details in
D5802), I've noticed a possible behavior-changing bug in context browser plugin.
(https://phabricator.kde.org/D5802)
The code seems to hint at using selection foreground for use-highlighted regions,
but uses normal foreground instead (which incidentally falls in line with behavior
for all other highlighting). I could just change it to avoid this uncertainty,
but the hinted-at behavior is what I want for Solarized.
