/**
 * Global `git -c` options that let a Windows checkout exceed MAX_PATH.
 *
 * Why command scope: Git for Windows aborts deep checkouts with "Filename too
 * long" unless core.longpaths is on, and `-c` applies it to this invocation
 * only — never `--global`, `--system`, or `--local`, so no user config is
 * written. Available since Git 1.9, well under the 2.25 baseline.
 *
 * Why keyed off cwd rather than a wslDistro option: a `C:\...` cwd can still be
 * served by host git.exe even when a distro is configured, and Linux git parses
 * and ignores the key, so only a true `\\wsl.localhost\...` path opts out.
