[PATCH 12/13] pretty: drop unused strbuf from parse_padding_placeholder()

[Jeff King <peff@peff.net>]

Unlike other parts of the --pretty user-format expansion,
this function is not actually writing to the output, but
instead just storing the padding values into a context
struct. We don't need to be passed a strbuf at all.
