I think we have only one more user for this function:
builtin/commit.c: ret = run_hook_ve(hook_env.argv,name, args);
The other function 'run_hook_le' is used in a few places:
builtin/am.c: ret = run_hook_le(NULL, "applypatch-msg",
am_path(state, "final-commit"), NULL);
builtin/am.c: if (run_hook_le(NULL, "pre-applypatch", NULL))
builtin/am.c: run_hook_le(NULL, "post-applypatch", NULL);
builtin/checkout.c: return run_hook_le(NULL, "post-checkout",
builtin/clone.c: err |= run_hook_le(NULL, "post-checkout",
sha1_to_hex(null_sha1),
builtin/gc.c: if (run_hook_le(NULL, "pre-auto-gc", NULL))
builtin/merge.c: run_hook_le(NULL, "post-merge", squash ? "1" :
"0", NULL);
builtin/receive-pack.c: if (run_hook_le(env->argv,
push_to_checkout_hook,
Would it be an option to just use the new function signature
everywhere and remove the wrapper? Or do we value the old interface?
