Why would this file be created?

Not sure why, but it was created in my Windows checkout and contains:
[core]
        autocrlf = false
        filemode = false

Same here.

This was also created in my Windows checkout and contains .ssh/config and
.ssh/known_hosts.

I think both .gitconfig and .ssh were created here originally as in Windows
depot_tools installs ssh and git. I now notice however that I also have these in
my homedir (i.e. %USERPROFILE% which for me is C:\Users\gab).

The files are identical, so I'll delete them for now and see if they later
reappear in depot_tools\

Actually... I recently set a HOME environment variable pointing to my homedir on
Windows to fix another problem I had (maybe that also forced .ssh\ and
.gitconfig to land in my home, but that wasn't the default (hence the legacy
files left behind))
