It looks like r29525 changes the behavior of Ctrl-Shift-C, which currently copies the log without changed paths (done in the else statement.) I didn't want to remove that behavior so I was adding separate hotkeys.
Here's what was missing from the patch if you want to try it again...
In resource.h, I added a new command:
#define ID_POPUP_UPDATEALL 32877
#define ID_LOGDLG_MONITOR_CLEARERRORS 32878
#define ID_LOGDLG_COPYREVISIONS 32879
In TortoiseProcENG.rc I added two new hotkeys:
IDR_ACC_LOGDLG ACCELERATORS
BEGIN
"C", ID_EDIT_COPY, VIRTKEY, CONTROL, NOINVERT
"C", ID_EDIT_COPY, VIRTKEY, SHIFT, CONTROL, NOINVERT
"C", ID_LOGDLG_COPYREVISIONS,VIRTKEY, ALT, CONTROL, NOINVERT
"R", ID_LOGDLG_COPYREVISIONS,VIRTKEY, CONTROL, NOINVERT
