Description
Currently, statusline segments have custom highlight groups, but the separators between the segments don't get any highlight group applied, resulting gaps/discontinuities in the statusline background with most colorschemes. This PR applies the highlight group provided to
trouble.statusline, if any, to the separators as well as to any segments that don't supply their own highlight group.The fix involves a slight refactor of the
fix_statuslinefunctionality such that segment hl backgrounds are substituted in advance rather than via post hoc search and replace.I also added a clause to filter out empty segments which would otherwise result in extraneous separators, usually appended to the end of the statusline string. Let me know if these empty segments/extra separators were intentional and I'll revert that change.

The author closed the issue when a workaround was posted, but I figured it would be worthwhile to fix this properly in the plugin.
