 Set compression level to @var{n} for the ZIP and ZLIB compression
 algorithms. The default is to use the default compression level of zlib
 (normally 6). @option{--bzip2-compress-level} sets the compression level
 for the BZIP2 compression algorithm (defaulting to 6 as well). This is a
 different option from @option{--compress-level} since BZIP2 uses a
 significant amount of memory for each additional compression level.
-@option{-z} sets both. A value of 0 for @var{n} disables compression.
-A value of -1 forces compression using the default level.

 Except for the @option{--store} command compression is always used
 unless @command{gpg} detects that the input is already compressed.  To
-inhibit the use of compression use @option{-z0}; to force compression
-use @option{-z-1} or option @option{z} with another compression level
-than the default as indicated by -1.  Note that this overriding of the
-default deection works only with @option{z} and not with the long
-variant of this option.
