From e880b1fea8442b623d45a8f62227fc35cbcac7ec Mon Sep 17 00:00:00 2001 From: Denys Vlasenko Date: Sun, 16 Feb 2020 18:31:05 +0100 Subject: 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.
