Error parsing selector with escaped colon at the end

[jsdw]

Using libsass 3.5.2 (via node-sass 4.8.3), The following leads to an error:

$ echo -e 'something\:{ padding: 2px; }' | ./node-sass
{
  "status": 1,
  "file": "stdin",
  "line": 1,
  "column": 1,
  "message": "Invalid CSS after \"s\": expected 1 selector or at-rule, was \"something\\\\:{ paddin\"",
  "formatted": "Error: Invalid CSS after \"s\": expected 1 selector or at-rule, was \"something\\\\:{ paddin\"\n        on line 1 of stdin\n>> something\\:{ padding: 2px; }\n\n   ^\n"
}

Adding a space between the colon and opening curly bracket works, eg:

$ echo -e 'something\: { padding: 2px; }' | ./node-sass
something\: {
  padding: 2px; }

This is a regression, and does not appear to be a problem using libsass 3.5.0.beta.2 (via node-sass 4.5.3).

My gut reaction is that this is not valid CSS syntax. If this word previously it may have been a bug that was patched. I'll confirm when I'm at a keyboard.

Confirmed this is a regression in 3.5.0.
