Thanks for noticing this, I stole this from bindings.el,
but now that repeat-echo-mode-line-string is highlighted
correctly in the mode-line, I wonder if such property is needed
for repeat-echo-mode-line-string at all?  And why it was needed
for mode-line-defining-kbd-macro to keep its text properties?

After removing this line from bindings.el:
  (put 'mode-line-defining-kbd-macro 'risky-local-variable t)
mode-line-defining-kbd-macro loses its text property
face=font-lock-warning-face, but repeat-echo-mode-line-string keeps it.

This is explained in (info "(elisp) Properties in Mode"),
but I don't understand why text properties are preserved for
repeat-echo-mode-line-string without ‘risky-local-variable’ property?

Strange, I see it immediately after C-x o.
