Thanks for pointing out the case when the command is bound to the same key
globally and in the repeat map.  So checking for a key can't help here.

Therefore, I implemented another solution in repeat.el.  There is now
a new symbol property 'repeat-continue-only'.  And a command with this
symbol property will not activate the repeat map, but will only continue
the already activated repeating sequence.   This is implemented by
a simple change:

      (when (and (repeat-check-map map)
                 (or (null (repeat--command-property 'repeat-continue-only))
                     was-in-progress))

Also I improved the existing tests to use more mnemonic keys:

  a - Activate (enter),
  c - Continue,
  o - continue-Only (not activate),
  q - Quit (exit)

Currently the test uses (put 'repeat-tests-call-o 'repeat-continue-only t)
but a new keyword ':continue-only' will be added to 'defvar-keymap'.

The same way you could try to use the new symbol property for 'bind-keys'.

I wrote a new test for 'bind-keys' in test/lisp/repeat-tests.el.
But the part for :continue-only is currently commented out.

BTW, while writing the 'bind-keys' test, I noticed there is no way
to specify a command that only activates, but not continues
(the same as :entry in 'defvar-keymap').  Is it true that 'bind-keys'
has no such keyword, so there is a need to do this explicitly with:

  (put 'repeat-tests-bind-call-a 'repeat-map 'repeat-tests-bind-keys-repeat-map)
