ash: optimize tryexec(): avoid one allocation
There was a bug in tryexec which bbox had fixed in 2003.
dash had a smaller fix in 2007. Copy it. It is smaller,
although it is also more quirky (requires argv[-1] to exist).
Upstream commit 1:
Date: Mon, 15 Oct 2007 20:24:28 +0800
[EXEC] Fixed execing of scripts with no hash-bang
The function tryexec used the original name instead of the path found through
PATH search. This patch fixes that.
Test case:
trap 'rm -f $TMP' EXIT
TMP=$(tempfile -s nosuchthing)
cat <<- EOF > $TMP
echo OK
EOF
chmod u+x $TMP
cd /
PATH=${TMP%/*} ${TMP##*/}
Old result:
/bin/sh: Can't open filelgY4Fanosuchthing
New result:
OK
Upstream commit 2:
