First of all, thanks for giving it a try!

Should be fixed.

In principle yes, unless there is a good reason to deviate. I tried
basing the implementation on the manual page and occasionally on the
source if something wasn't clear.
Does there exist a more formal standard/description of the command language?

Yes this was the case, it should be fixed now.

It is mainly for convenience. In the past (before the command line was
implemented as a regular file) <Tab> was ignored because lots of vim
users would try to auto complete stuff. Also tab expansion also applies
to the command line, hence depending on your setting you might not get a
literal tab character. This can be worked around with <Ctrl-v><Tab>. The
same can also be used to enter multi line commands. But to actually
execute them one has to mark the selection to execute in visual mode and
then press <Enter>.

Please report more examples of the bugs you encountered.

Haven't really looked into it yet. The problem might be that . also
matches new lines.
However the "idomatic" way to do this seems to be `x i/FOO` which
works.

This might be better indeed. I will see what I like more ...
