Quotes detokenized incorrectly

[evgenyrp]

Example:

“See what you have done!” she screamed. “In a minute I shall melt away.”

tokenized:
['“', 'See', 'what', 'you', 'have', 'done', '!', '”', 'she', 'screamed', '.', '“', 'In', 'a', 'minute', 'I', 'shall', 'melt', 'away', '.', '”']

detokenized:
“See what you have done! ” she screamed.“ In a minute I shall melt away. ”

Expected: spacing is the same as in the the original sentence
Actual: extra whitespace near the quotes
