Nice approach indeed!
Could be curtailed to
Code:
sed -r "/'($(paste -sd\| file2))'/s/^C//" file1

, including the item list file as well.

NAME
dmenu - dynamic menu SYNOPSIS
dmenu [-b] [-i] [-l lines] [-m monitor] [-p prompt] [-fn font] [-nb color] [-nf color] [-sb color] [-sf color] [-v] dmenu_run ... dmenu_path DESCRIPTION
dmenu is a dynamic menu for X, originally designed for dwm(1). It manages huge numbers of user-defined menu items efficiently. dmenu reads a list of newline-separated items from standard input and creates a menu. When the user selects an item or enters any text and presses Return, their choice is printed to standard output and dmenu terminates. dmenu_run is a dmenu script used by dwm which lists programs in the user's PATH and executes the selected item. dmenu_path is a program used by dmenu_run to find and cache a list of executables. OPTIONS
-b dmenu appears at the bottom of the screen. -i dmenu matches menu items case insensitively. -l lines dmenu lists items vertically, with the given number of lines. -m monitor dmenu appears on the given Xinerama screen. -p prompt defines the prompt to be displayed to the left of the input field. -fn font defines the font or font set used. -nb color defines the normal background color. #RGB, #RRGGBB, and color names are supported. -nf color defines the normal foreground color. -sb color defines the selected background color. -sf color defines the selected foreground color. -v prints version information to standard output, then exits. USAGE
dmenu is completely controlled by the keyboard. Besides standard Unix line editing and item selection (Up/Down/Left/Right, PageUp/Page- Down, Home/End), the following keys are recognized: Tab (Control-i) Copy the selected item to the input field. Return (Control-j) Confirm selection. Prints the selected item to standard output and exits, returning success. Shift-Return (Control-Shift-j) Confirm input. Prints the input text to standard output and exits, returning success. Escape (Control-c) Exit without selecting an item, returning failure. Control-y Paste the current X selection into the input field. SEE ALSO
