[BUG] Repeating an edit command with dot (.) doesn't work in some situations

Reproducer

When solving the VimGolf challenge Increment number for every 10 lines and repeating the previous A with a dot (.) inside a macro:

j9JCCQA,<c-r>#<esc>kQ9qggQj9C.,Qqq<space>q

Another example is maximun and minimun.

It's not a practical solution (that would be %<a-s><a-!>jq min,max<ret>), but anyway:

O0<esc><a-o>4330o<c-r>#<esc>
%Q<a-m>Zs\d+<ret>*
[p<a-.>s<ret><c-s>
,yza<space><space><esc>p<c-o>
yz..p.a<lt><gt><esc>kQ39q
<a-.>d%<a-s><a-t>]&e&<space>q

Outcome

The dot command does nothing. In the second example, it works when defining the macro within Q...Q, but not when repeating it with q.

Introduced with dbe8528

Expectations

The dot command appends comma following by a number (1st example) resp. two spaces (2nd example)

Additional information

Probably related to #5120

I think this should be fixed by 6598d7b can you confirm ?

[schragge]

No, unfortunately, that commit indeed fixed the crash, but didn't fix the dot problem. Moreover, I'm now seeing another strange behavior, perhaps unrelated: when selecting a series of numbers with s\d+<ret>, stand-alone zeros don't get selected. E.g.

c1 2 0 3<esc>xs\d<ret>
