Yes, apologies. I have two copies of git and emacs keeps finding the
right one, but my msys buffer does not.

Thanks for this and the style comments.

My reasoning was that (i) it was easy to do while I was watching
COVID-19 news and (ii) on top of this one can almost trivially build a
file handler for *.gz files that does not require gzip (as in the
automatic compression mode). Currently *-deps.zip ships all types of
compressors, including zlib, but not gzip. There may be other use cases,
such as the Emacs web server by E. Schulte (uses zlib-flate and
gzip). But I understand if you find it yet another maintenance hassle.
