Format long values on a single line

[nyurik]

Continuing from #68

Per issue reported for Wikidata Query Service, please format multiple VALUES on a single line when they can fit. Examples:

Original text

SELECT * WHERE {
  VALUES ?a { wd:Q1 wd:Q2 ... }
}

Desired results

# short list
SELECT * WHERE {
  VALUES ?a { wd:Q1 wd:Q2 }
}

# long list
SELECT * WHERE {
  VALUES ?a {
    wd:Q1 wd:Q2 wd:Q1 wd:Q2 wd:Q1 wd:Q2 wd:Q1 wd:Q2 wd:Q1 wd:Q2 wd:Q1 wd:Q2
    wd:Q1 wd:Q2 wd:Q1 wd:Q2 wd:Q1 wd:Q2 wd:Q1 wd:Q2 wd:Q1 wd:Q2 wd:Q1 wd:Q2
  }
}

Current result

SELECT * WHERE {
  VALUES ?a {
    wd:Q1
    wd:Q2
  }
}

Define "fit"?

Per max line length config parameter (for most code its usually ~120ish(?), but obviously configurable). So if the whole VALUES fits on a single line, use it, otherwise use the long list format. Thx!
