viewer in hex mode sometimes shows "-" incorrectly

[Peter Schmitt]

Midnight commander:

Curious bug of "View Hex":
Depending on the name of a file (with or without extension .2)
      and on the directory(!)
the internal viewer with the hex option shows
the 1-byte ASCII character "-"
    as (incorrectly) as 3 bytes "E2 80 90"
    or (correctly) as 1 byte "2D".
This is demonstrated by screen shots taken with a 6-byte file,
but was discovered accidently with a larger file.
