Merge branch 'cp/git-flush-is-an-env-bool' into maint-2.43
Unlike other environment variables that took the usual true/false/yes/no as well as 0/1, GIT_FLUSH only understood 0/1, which has been corrected. * cp/git-flush-is-an-env-bool: write-or-die: make GIT_FLUSH a Boolean environment variable

based on whether stdout appears to be redirected to a file or not.
