Editing compressed files with Vim bzip2 compress
1. Autocommands gzip-autocmd
The functionality mentioned here is a standard-plugin. This plugin is only available if 'compatible' is not set. You can avoid loading this plugin by setting the "loaded_gzip" variable:
:let loaded_gzip = 1

1. Autocommands gzip-autocmd

The plugin installs autocommands to intercept reading and writing of files with these extensions:
extension compression
.Z compress (Lempel-Ziv) .gz gzip .bz2 bzip2 .lzma lzma .xz xz .lz lzip .zst zstd
That's actually the only thing you need to know. There are no options.
After decompressing a file, the filetype will be detected again. This will make a file like "foo.c.gz" get the "c" filetype.
If you have 'patchmode' set, it will be appended after the extension for compression. Thus editing the patchmode file will not give you the automatic decompression. You have to rename the file if you want this.
