Skip leading whitespace in style name.

Found by Clang-Tidy. The intent seems to have been to skip all leading
whitespace in the 'style' string, but instead this loop was an odd
looking no-op. Remove the 'break' from the loop so that it will
continue until end of string or a non-space character is found.
