I sometimes work in files where I cannot remove trailing whitespaces (at
least not permanently). In these cases the background highlighting of
them is quite strong and can be a bit annoying. To make this more
pleasing, use the foreground to highlight trailing characters, as long
as tabs and trailing spaces are displayed as non-space characters.
For this I also set `trail` in `&listchars`, and while at it, merged the
two lines setting `&listchars` and cleaned up some comments.
This makes it a lot easier to restrict the search (besides searching in
visual selection, which is quite limited). The cursor will still land on
the closed fold but only once, independent of the number of hits inside
of the fold.
I rarely use them and are more an annoyance.
For the case that I want to enable them in a session, move the
numbertoggle augroup into a function and add an autocommand on
`OptionSet relativenumber`.
Step by step I want to restructure the vim files. The approach to
cleanly divide the config by topics works in zsh pretty well, but is too
vague in vim for my liking.
Especially (the very small) functions and autocommands that have the
purpose of setting options or mapping keys or the interplay of multiple
categories together, make it difficult to decide in which file the
snippets should lay.
Use `gitgutter`'s `foldtext()` to display an indicator if a fold
contains lines that have been changed.
This is necessary as {,neo}vim does not display signs next to folded
lines.
Do not automatically restore missing <EOL> at EOF when writing.
This is rarely a change worth committing and I'd rather prefer vim to
not touch stuff I did not actively modify myself.
