Indeed, it is a problem present in 4.5.55. I made a screenshot
available at http://www.internet-treff.uni-koeln.de/~martin/dump.gif

Notice, how moving the selection over these files inserts characters
into the command prompt.

GNU Midnight Commander 4.5.55
Edition: text mode
Virtual File System: tarfs, extfs, ftpfs, mcfs, undelfs
With builtin Editor
Using S-Lang library with terminfo database
With subshell support as default
With support for background operations
With mouse support on xterm and Linux console
Using locale "C" (from environment variable LC_MESSAGES)
