Lines containing a carriage return alone, followed by color escape
sequences, are not colorized properly.
A carriage return in the compilation buffer is interpreted by erasing
contents since the beginning of the line, but compilation-filter-start
is not updated accordingly before calling the filter-hooks.
Workaround it by always colorizing a region from to the beginning of the
line where compilation-filter-start points.
Create new layers:
- spacemacs-navigation: contains packages whose principal goal is navigation
- spacemacs-modeline: contains packages about mode line
Merge spacemacs-ui and spacemacs-ui-visual into layer spacemacs-visual.
