Re: [Bug-readline] How does readline know where words end (psql and yank-last-arg use case)?

In this case, since you're yanking from the history, it uses the history
library's set of word delimiters.  In general, it uses the notion of
characters that break words.

The history library's set of word delimiters is a subset of the shell's:
` \t\n;&()|<>', with quoting honored.

There aren't any hooks to modify this from outside the history library.
