Thanks, it looks good. The other recursive call to quotearg_buffer_restyled return quotearg_buffer_restyled (buffer, buffersize, arg, argsize, quoting_style, flags & ~QA_ELIDE_OUTER_QUOTES, NULL, left_quote, right_quote); is also OK, because the code is careful not to make more than one STORE (...) call per input byte if elide_outer_quotes is true. There are enough occurrences of if (elide_outer_quotes) goto force_outer_quoting_style; so that the string that was produced before this recursive call will not be longer than the one produced by the recursive call. => All fine.
