Extra newline in git log with tformat

Question

When I use git log --pretty=oneline --shortstat, I get a compact representation of my log:

% git log --pretty=oneline --shortstat

But if I try to use the tformat equivalent of oneline, I get an extra newline before the stat:

% git log --pretty="%C(yellow)%H%Creset %s" --shortstat

Without the --shortstat flag (or --stat) flag, the output of the two commands is identical, so it's something about adding those flags.

I can fix this with grep:

[alias]
  x-skip-empty-lines="!f(){ git $* --color=always | grep -vE '^(\\|{0,1}|\\e\\[[^m]*m)[[:space:]]*$' | less ;}; f"
  logpatch= !git x-skip-empty-lines log --pretty='%C(yellow)%H%Creset %s' --shortstat 

But is there a way to avoid producing the newline in the first place?

I'm afraid that there's nothing you can do about that. In log-tree.c, git has a special case for the oneline format, and always outputs two blank lines before the shortstat if it is not used.

(I've tried to compile git-log without the highlighted line - the original --pretty=oneline command then also outputs two blank lines)
