Yuck. If you really have to quote, it is often far simpler to take
advantage of the fact that quoting rule for shell is much simpler
inside '', i.e.
sub sq {
my ($string) = @_;
$string =~ s|'|'\\''|g;
return "'$string'";
}
The only thing you have to worry about is a single quote, which
would close the single quote you want to be in, and you express it
by first closing the single quote you opened, put the single quote
by emitting a backslash and a single quote, and then immediately
open another single quote.

I'll leave this part to Peff to comment on.

I think it is saner to do something like this instead here:
$mach = { machine => undef }
Otherwise your log_debug() will be filled by the tokens used for the
default entry, and also this "undef $mach" here will break your
macdef skipping logic if the default entry has a macdef, I think.
You can ignore an entry with undefined "machine" in the loop at the
end of load_netrc.

Otherwise, looks almost ready to me.
Thanks.
