fix: md-code specs/attribs

[Valexr]

Simple fix #401

export function parseTag(input) {
  const { str, getValue } = valueGetter(input)
  const strings = str.split(/\s+/)
  const specs = strings.filter((s, i) => !i || s.match(/^[#|.]/)).join('')
  const attribs = strings.filter(s => !specs.includes(s))
  const self = { ...parseSpecs(specs), data: {} }
  ...

Nue has a VERY GOOD IDEAs 👍🏻, but I think it's needed semantic specs & convention for more neat, structured & easy maintained codebase 🤔

Thanks!

The challenge here is that "neat" or "structured" are subjective. Hope we find a good/satisfying balance as we move forward.
