Refs #1258.

In a config [[table]] glob, {name} no longer means *; it is a literal, as in a path-table and in bash. Breaking: write *. A {a,b} alternation is unchanged.

Checked by hand: {name}.md matches only a file literally named {name}.md on a config table and a path-table, as bash does.

Red commit: d9fccfa, CI run 37404008088 (a_braced_name_is_not_a_wildcard left ["x.md", "{name}.md"], right ["{name}.md"]).

Removes the {name} placeholder grammar and the now-meaningless CaptureColumnCollision error, plus tests of both.
