gpg: fix --enarmor with zero length source file
* common/iobuf.c (filter_flush): Remove "src_len == 0" check. * g10/compress-bz2.c (do_compress): Exit early if flush not forced and input length is zero. * g10/compress.c (do_compress): Likewise. -- Remove "(src_len == 0)" check in filter_flush which was introduced to fix compress failure caused by zero length flush from iobuf_close. However this check broke enarmoring file with length of zero. Patch instead fixes zero length flush problem in compress filters. GnuPG-bug-id: T5828 Signed-off-by: Jussi Kivilinna <[email protected]>
