#99 Don't auto-complete df$VAR to df[["VAR"]]

[Milan Bouchet-Valat]

Auto-completion always transforms the $ operator into [[]]. This is annoying, because you need to manually close the quote and the double brackets, which are quite hard to reach on many keyboard layouts. It's less efficient than typing the full name of the variable by hand! I think the $ should be kept as-is.
