[patch] Command-line window first character was erased when CTRL-C typed and 'conceallevel' option greater than 0.

[h_east]

Hi Bram and Vim addicts :-)

How to reproduce. (I checked Vim 7.4.728 on fedora 20 via PuTTY 0.64)
- Start Vim and conceallevel=1
  $ vim -u NONE -i NONE -N -c 'set conceallevel=1'
- Display command-line window
  q:
- Cancel command-line window
  CTRL-C

Expected behavior.
- Cursor move to command-line and displayed command-line window very well.

Actual behavior.
- Command-line window first character(:) was erased.


I attached a patch.
Please check and include this.
