Problem

#10952 added -C to solve #10098 and reduce #2930's impact but we couldn't get buy-in on a name and shipped it as-is to not block the feature on the long name as -C by itself has enough use within the community

Proposed Solution

From ehuss:

I don't have a strong opinion about the long name. --cwd or --cd seems more explicit as to what it does, and would lean slightly towards that, but other options seem fine. -C seems to be the most common for a short flag.

A quick survey:

• make: -C or --directory
• git: -C
• Meson: -C
• ninja: -C
• hg: --cwd
• Gradle: -p, --project-dir?
• Julia: --project?
• Swift: -working-directory?
• dub: --root
• msbuild: passed as first argument
• npm: n/a
• Ivy: n/a?
• Maven: n/a?
• Bazel: n/a?
• Buck: n/a?
• go: -C
• nuget: n/a?
• sbt: n/a?
• dart: -C or --directory

Other command line tools with similar flags:

• tar: -C or --directory (BSD tar has --cd)
• ls: -d or --directory to list directories
  • rm: -d or --dir to remove directories

Plus the stdlib calls this "current dir" (std::env::current_dir, std::process::Command::current_dir) so we could name it --current-dir
