{..|..} reported a repeated arm rather than a reference with no path, and
{|} reported one rather than a missing field. Both are load errors either
way, but the repeat is a consequence of the real mistake, so the real one
should be what the author reads.

{a|a|b} skews an alternation three to one, an undocumented third way to
weight beside a choice's weight and a repeated choice entry. These pin its
rejection, and one accepted case fixes the boundary: {x}{x} is two tokens,
so it stays two independent draws.

A dot is already rejected in a category, folder or field name. The token
grammar reserves three more characters: '|' separates a token's arms, '('
opens a function call, and '}' ends the token. A name carrying one resolves
by dot path and is advertised by List, yet no format can name it.
These pin the rejection, and one accepted case fixes the boundary: ')' on
its own is spellable, so it stays legal.
