@srdo : I actually spent extra effort to have 2 commits. :-) This was to
ensure that there is no hidden changes amidst the renaming of the file (I am a
strong proponent of trivial-to-read commits/diffs). With the 2 separate
commits, in raw CLI `git` the changes are easy to follow. When I made the
change at first in 1 commit I believe it was hard to see within the `git show`
what lines had been touched. I might be misremembering a bit, but I definitely
remember that it was clear in the `git status` that a non-content-changing
rename was done, so long as I didn't touch the file contents simultaneously.
