3. try to review first commit hg review -c 0 -w manvel@adblockplus.org -t "..."

Observed behaviour

Got error status from ['hg', 'status', '--rev', '0^{:0', '-u', '.']:}

Expected behaviour

Review uploaded.

For reference, selecting the correct revision range here is possible with -r 00000000:0 but I see a way to select any changeset in a generic way (0^:0 fails because the initial commit doesn't have a parent so this range is empty).

I thought that I solved this - 0^+null+0 and 1^+null+1 produce correct results with both hg diff and hg status. However, upload.py also uses hg cat in order to retrieve the base files. While it recognizes the a:b for for revision sets and extracts the base revision correctly then, anything more advanced won't work. I also tried (0^+null):0 and (1^+null):1, but hg cat --rev '(1^+null)' won't work correctly either.
