I don't think that exists until the next patch. :) I think just trimming from the front is OK, though, because color_parse_mem() trims trailing whitespace after a word. So either you have a word and we will trim after it, or you do not (in which case this will trim everything and hit the !len case you added). So maybe a better commit message is just: Normally color_parse_mem() is called from config parser which trims the leading spaces already. The new caller in the next patch won't. Let's be tidy and trim leading spaces too (we already trim trailing spaces after a word). -Peff
