This is very much the designed behaviour, I would think. IIRC, the user-format support of "rev-list" was designed so that the scripts can customize the output from "rev-list -v", which was how scripts were expected to read various pieces of information for each commit originally. And the 40-hex commit object name and/or a line that begins with "commit ..." when a user format is used are meant to serve as stable record separator (in that sense, having %H or %h in the userformat given to rev-list is redundant) when these scripts are reading output from "rev-list".

A new option to tell "rev-list" that "I am designing an output that is a-line-per-commit with the userformat and do not need the default record separator" or "I will arrange record separator myself" would be an acceptable thing to add, provided if many scripts yet to be written would benefit from such a feature, though.
