Bug#482776: vim: creates undeletable buffer when "set hidden" is enabled

[Marc Lehmann]

Package: vim
Version: 1:7.0-122+1etch3
Severity: normal


vim-7.1.293-3 created undeletable buffers when the hidden option is set.

how to reproduce:

   echo "set hidden" >$HOME/.vimrc
   vi somedir/CVS   # it must be a CVS directory

this creates a netrw buffer:

   " ============================================================================
   " Netrw Directory Listing                                        (netrw v119)
   "   /localvol/root/src/EV/t/CVS
   "   Sorted by      name
   "   Sort sequence: [\/]$,\.h$,\.c$,\.cpp$,\.[a-np-z]$,*,\.info$,\.swp$,\.o$\.obj$,\.bak$
   "   Quick Help: <F1>:help  -:go up dir  D:delete  R:rename  s:sort-by  x:exec
   " ============================================================================
   ../
   ./
   Entries
   Repository
   Root
   ~
   ~
   "t/CVS" is a directory                                 8:01 66% + 460 0x2E  46

when the :bd command is used, the lowest line changes to:

   "[Scratch]" [RO] 12 lines --66%--                      8:01 66% + 460 0x2E  46           

:ls shows

     1 #h   "t/CVS"                        line 1

I have not found a way to delete this buffer.

Removing either the set hidden option from my .vimrc, or using vim from
stable fixes this problem.
