Also removes last use of
shell=Trueuse for command invokation for defense-in-depth.Context
I was trying to eliminate the last usage of
shell=Trueinsubprocess.Popen, then had to resort to usingshlex.splitinedit_files. This led me into the rabbit hole ofshlex.splitusage in_termui_impl.pyfile. Which I use as an opportunity to document past choices from older issues and PRs.Tests
I also use that opportunity to collect test cases discussed in older related issues and PRs to illustrate and cover how we are expecting command path to be unquoted and interpreted on POSIX systems and Windows.
