--[[ Core behavior: bash as the shell, confirm prompts, shared clipboard, fast `CursorHold`.
`shell` pins shell commands to bash regardless of the login shell.
`confirm` asks instead of failing when a command would discard unsaved changes.
`clipboard` syncs the unnamed register with the system clipboard.
`updatetime` shortens the swap-file write interval and the `CursorHold` delay to one second.
Removing `B` from `cpoptions` makes `\` escape like `CTRL-V` in mappings, abbreviations and user
commands — useful for matching mappings that start with space: `:map \ `. ]]

files by default; `:grep {args}` appends to it, so widen a single invocation with:
`-.` also search hidden files (e.g. dotfiles), still skipping `.gitignore`d paths
`-uu` also search hidden and `.gitignore`d files (descends into `.git/` too)
`-uuu` `-uu` plus binary files
Appending `**` to `path` lets `:find` and `gf` resolve a filename anywhere below the cwd — the
default `.,,` searches the current file's directory and the cwd, `**` adds every directory beneath
it. ]]

`conceallevel` hides text carrying the "conceal" syntax attribute.
`showtabline` always shows the tabline;
`winborder` rounds the outline of floating windows.
`list` shows non-printables with the `listchars` markers: trailing spaces as `-`, non-breakable
spaces as `+`, and `→`/`←` where text continues past the window edge when `wrap` is off (the blank
`tab` value keeps tabs invisible).
