Yes, thank you! This is something that has bugged me
for a while. This change is actually a regression (or
else on purpose?), introduced in Emacs 24. In all
Emacs releases prior to 24 it works as a user expects.
Dunno whether this bug report might be a duplicate. It
seems unlikely that no one (including me) has reported
this before. It reduces the utility of `C-x ESC ESC'
considerably.
An inexperienced user will likely give up altogether
trying to use such a command with `C-x ESC ESC', if
not give up on `C-x ESC ESC' entirely, through not
fully understanding. And an experienced user has
the annoyance of having to edit the hard-coded values
to get the behavior expected.
