Bug#309928: vim-common: gzip files are uncompressed after :w

[Carlos Z.F. Liu]

Package: vim-common
Version: 1:6.3-071+2
Severity: normal

I have a text file with gzip compression. After I open it by vim, and
edit a bit, and ":w" it, vim show following error msg:

Error detected while processing function <SNR>14_write:
line    7:
E121: Undefined variable: b:compression
E116: Invalid arguments for function system(a:cmd . " " . b:compression
.. " " . nmt)

And then, the file will be saved as a plain text file, aka uncompressed.
