repeat last command doesn't work with replace char command

[JohnCoconut]

In vim, r is used to replace a single char with another, . is used to repeat last command. However, this two does not work together here.

For example, I have

#abc
#abc
#abc

If I use r to replace first # with ., it changes to

.abc
#abc
#abc

However, when I move to second line, use . command to repeat last command, I get

.abc
..abc
#abc

What I expect is

.abc
.abc
#abc

If I use . to repeat command in the third line, I get

.abc
..abc
....abc
