[PATCH 0/1] MR6535: ntdll: Set correct MaximumLength when current directory path is longer than MAX_PATH.

[Owen Rudge (＠orudge)]

Calls to `CreateProcessW` where the current directory is a path that exceeds `MAX_PATH` can result in `Length` exceeding `MaximumLength`, causing corruption in `alloc_process_params` when `append_unicode_string` copies the string according to `Length`, but only allocates `MaximumLength` of storage.
