clean as this function may be called more than once (e.g. from functions in --edit). * g10.c, encode.c (encode_crypt), sign.c (sign_file, sign_symencrypt_file): Make --compress-algo work like the documentation says. It should be like --cipher-algo and --digest-algo in that it can override the preferences calculation and impose the setting the user wants. No --compress-algo setting allows the usual preferences calculation to take place. * main.h, compress.c (compress_filter): use new DEFAULT_COMPRESS_ALGO define, and add a sanity check for compress algo value.
