dmenu_run doesn't really run the user input as a shell command line.
For instance, run dmenu_run from a terminal, then in the menu type:
echo hello\ world
The terminal output is "hello\ world" instead of "hello world".
`eval' solves the problem, but when it comes to eval, I can't really
be sure, so please point out the possible errors/risks.
`LC_ALL=C' is for sort.
