What to draw after the cursor on a path line: the rest of the shortest path that continues it.

pathSuggestion and not suggest, because suggest is what this file already imports for the OTHER kind of suggestion — the one made from names the page has and from history. Two suggests in one function, one of them namespaced, is what this used to read as.

Empty for a line that is not a path line, so a caller can fall through to that other one. Shortest for the same reason a name is: lib/ is what li meant far more often than the longest thing underneath it.

import { pathSuggestion } from './completion.ts';

pathSuggestion('document.ti', process.cwd()); // '' — not a path line, so not this one's answer
