As of a recent SVN HEAD, `d.legend' uses a static buffer to
store the value of the `map' option. It's therefore impossible
to pass raster names more than 63 bytes long to `d.legend'.
Since I don't see why a static buffer may be necessary here, I
suggest the following (yet untested) patch.
diff --git a/display/d.legend/main.c b/display/d.legend/main.c
index d827d04..324012d 100644

PS. I've seen a number of other uses of static buffers scattered across
the code, leading to both potential limits and crashes, which
I'm on the way to investigate.
