+/**
+ * Env pinning git subprocess output to untranslated English (issue #7808).
+ *
+ * Why: Orca parses git's stderr diagnostics and progress lines (e.g.
+ * isNoUpstreamError, clone progress/`fatal:` matching); a gettext-enabled git
+ * under a non-English locale translates even the `fatal:` prefix and silently
+ * breaks those parsers. An English UTF-8 locale rather than plain `C` keeps a
+ * UTF-8 LC_CTYPE for hooks git spawns (commit, push); a host without
+ * en_US.UTF-8 falls back to C, which still emits untranslated messages.
+ * LANGUAGE outranks LC_ALL in gettext's lookup, so it is pinned too.
