[patch] can not write a trail comment to the :hide command

[h_east]

Hi Bram and list,

How to reproduce:
- Start vanilla Vim with two buffers.
$ vim -Nu NONE -o a b
- buffer 'a' to modified.
:set modofied
- exec :hide command with trail comment
:hide " command

Expected behavior:
- :hide command succeed.

Actual behavior:
- Occurred 'E474: Invalid argument'

I wrote a patch. Of course contains a test.
Check it please.

Can you add a test that does something like this:

:hide echo "one|two"

To check that the bar is not recognized to separate commands?

Right, I added a test case.
Check an attached patch.

NOTE:
This issue was reported by Norio Takagi.
