So is life. :-\ In Unix shells (in bash and zsh, at least), ~ is
expanded by the shell, but only in the beginning of tokens. You'll
find the same behavior in other commands (compare "echo foo=~" and
"echo foo ~"). I don't want to expand ~ "by hand" inside LR because
that's not portable and not standard. I'd rather have LR support long
options with two tokens instead ("--only-from ~/path/to/repo"), but
that would be extra work to implement (it wouldn't fit easily with the
current decentralized scheme for option handling in LR).
