Bug#3096: lxtools: user error (misuse of -r and filename) gives coredump

[eichin@kitten.gen.ma.us (Mark W. Eichin)]

package: lxtools
version: 1.1-1

If I *mistakenly* give both -r and a source filename:

% lxcopy -r -8 -b 19200 foo1.zip a:pgp/
LXCOPY 1.1 by A. Garzotto

Collecting file names...
Segmentation fault
Exit 139

it crashes with a segfault. If I drop the '-r' argument, it does the
right thing, so this isn't much of a bug, but user error should still
not lead to core dumps :-)
