Fix #27505: Text Editor always indent next line when a " is found (which is not always correct)

Do not indent if there's any non-space character after colon.

This only makes life a bit easier, but it's still not 100% correct indentation
strategy. For example when colon is inside non-closed string or so.
Also there's not indentation for { and un-indentation for }.

Handling such cases would require much smarter strategy..
