ash: expand: Use HOME in tilde expansion when it is empty
Upstream commit: Date: Sun, 27 May 2018 17:31:57 +0800 expand: Use HOME in tilde expansion when it is empty Currently if HOME is set to empty tilde expansion will fail, i.e., it will remain as a literal tilde. This patch changes it to return the empty string as required by POSIX. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
