terminal: config -list should print strings in quotes (#2605)

Browse Source 
Commit 8e91d3b0b added a number of configuration options to control the
colors of sytnax highlighting, unfortunately 'config -list' will print
all of those to stdout without quoting them, resulting in the color of
the last one being applied to all subsequent text.

Change 'config -list' to print strings in quotes so that we don't
accidentally send escape sequences to the terminal.
