Just appending -l to $SHELL to create a login shell is wrong: -l is not POSIX,

Browse Source 
and some people may use shells which do not support it. Instead, make an empty
default-command option mean a login shell, and fork it with a - in argv[0]
which is the method used by login(1).

Also fix the automatic-rename code to handle this correctly and to strip a
leading - if present.
