Don't barf when ending a FAKE block

After updating, fish would immediately die when started in an xterm from
my window manager (wmii) with a message like:

fish: builtin.cpp:3357: int builtin_end(parser_t&, wchar_t**): Assertion `false' failed.
fish: Job 1, “~/code/fish-shell/fish” terminated by signal SIGABRT (Abort)

Starting fish from an existing shell worked, and running it on other
machines that I was only SSHing into worked as well. I did discover that
on one machine starting git from one specific directory
(/home/ian/bml/kernel) would cause this failure, but starting from any
other directory worked as normal. I'm not entirely sure what
circumstances contribute to this failure - starting from a copy of the
kernel directory works fine.

The failure only started with the following commit, which introduced the
assert(false):

commit d788c844408d25eb5f986d8c6e2b609270dbc153
Made type property of block_t constant and private
Further work towards cleaning up block_t hierarchy

Looking at this fail in gdb:

(gdb) r
Starting program: /home/ian/code/fish-shell/fish
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Program received signal SIGABRT, Aborted.

(gdb) up 3
3357                    assert(false); //should never get here
(gdb) p parser.current_block->type()
$1 = FAKE

So this happens when we run an end command for a FAKE block.

The below patch adds an empty case for FAKE blocks to avoid hitting the
assert. I would need to study the code in more detail to understand if
we should even be executing this code if we are in a FAKE block, but
this patch seems to solve the issue for me.

Package groups were completed as repos. Fixed.
By default fish expands arguments along with options. This is not desired,
so made sure they are expanded only when needed, for performance reasons.
