Last semicolon in file is not consumed

[mvorisek]

(originally posted in postcss as postcss/postcss#1806)

LESS

@variable: {
  field: something;
};

Actual Behavior

is currently parsed wrongly and the raws property (in postcss) contains:

raws: { semicolon: false, after: ';\n' },

Expected Behavior

but I would expect:

raws: { semicolon: true, after: '\n' },

Observations:

• the problem seems to be in lib/parser.js file

• the semicolon is not consumed only for the last LESS variable in file

• file like:

  @variable: something;
  

  (ie. variable without curly brackets) has the semicolon consumed correctly

I belive the problem is not here, but in prettier directly - see prettier/prettier#14007.
