make change-history

[Ken Brown]

I'd like to update ChangeLog.3 so that I can fix a typo in a commit 
message.  The commit was made on master.  According to the last sentence 
of admin/notes/repo, I'm supposed to run 'make change-history'.  But 
this doesn't currently work when master is checked out:

$ make change-history
git branch | grep -q '^\* emacs-26$'
make: *** [Makefile:1125: preferred-branch-is-current] Error 1

Can someone tell me how to deal with this (and/or update the 
instructions in admin/notes/repo)?

Thanks.

Ken
