Thank you! This is Interesting but tricky and not at all obvious. In
fact the help doesn't say anything about an optional count:

:[range]il[ist][!] [/]pattern[/]
Like "[I" and "]I", but search in [range] lines
(default: whole file).
See |:search-args| for [/] and [!]. {not in Vi}

This is also interesting. When I checked the help for 'search-args' I
read
[!] When included, find matches in lines that are recognized as
comments.
and I stopped reading. I didn't pay any attention to the explanation
about [!] and 'comments' because I thought it would not be relevant
for a buffer with no particular file type. Now I see I was wrong,
since vim has always some notion of what a comment is according to the
settings in the 'comments' option.

Thank you everybody for the help.
PS: ":ilist! 0 123" also works. I prefer this as it makes slightly
more clear that 0 is just a dummy value.
