conceal problem when I enable linebreak setting ...

[cs86661]

example:

1. open test.c.

2. change settings.
:set list
:set listchars=tab:\|-
:syntax match Conceal conceal cchar=> 'AB'
:set conceallevel=1

3. problem setting, some chars disappeared ?!
:set lbr

Concealing, linebreak and listlbr features are getting considerably
complex. It is hard to understand what is going on.

I made a patch, that I think fixes this bug and includes a test as well,
but understanding that part of the line drawing code is quite complex. I
hope this doesn't cause any problems.

Thanks, I'll put it on the list.

Conceal has always been a bit problematic. Linebreak isn't simple
either. So yes, the combination is very complex. And then we like to
keep it fast as well...

thank you. I patch it into vim 7.4.542. It seems to be correct ...almost!

I found it has another problem, maybe I should not use this conceal feature. :(

example:

1. open test_2.c.

2. change settings.
:set list
:set listchars=tab:\|-

:syntax match Conceal conceal cchar=> 'MSG_MODE_'
:set conceallevel=1

3. problem setting, some tab char replace by spaces.
:set lbr

Please check attached patch. That should fix both your problems and
includes a test.

Thanks. Does this replace the patch of two days earlier?
