Bug#360118: vim: doesn't set 'fileencoding' for compressed files

[Jakub Wilk]

Package: vim
Version: 1:6.4-007+1
Severity: normal
Tags: l10n

vim doesn't set the 'fileencoding' variable for compressed files, 
despite the fact it correctly recognizes the actual file encoding 
(non-ASCII characters are shown properly).

$ grep encoding .vimrc
let &termencoding=system("locale charmap | tr -d '\n'")
set encoding=utf-8
set fileencodings=utf-8,iso-8859-2

$ printf '\xd3\xf3ps\n' > foo

$ od -t x1 foo
0000000 d3 f3 70 73 0a
0000005

$ vim foo
:set fileencoding
  fileencoding=iso-8859-2
:q

$ gzip foo; zcat foo.gz | od -t x1
0000000 d3 f3 70 73 0a
0000005

$ vim foo.gz
:set fileencoding
  fileencoding=
:wq

$ zcat foo.gz | od -t x1
0000000 c3 93 c3 b3 70 73 0a
0000007
