ash: [PARSER] Recognise here-doc delimiters terminated by EOF
Upstream commit 1:
Date: Wed, 26 Sep 2007 17:14:16 +0800
[PARSER] Recognise here-doc delimiters terminated by EOF
Previously dash required a <newline> character to be present in order for
a here-document delimiter to be detected. Allowing EOF in the absence of
a <newline> to play the same purpose allows some intuitive scripts to
succeed. POSIX seems to be silence on this so this should be OK.
Test case:
eval 'cat <<- NOT
test
NOT'
echo OK
Old result:
test
NOTOK
New result:
test
OK

[PARSER] Fix here-doc corruption
The change
[PARSER] Recognise here-doc delimiters terminated by EOF
introduced a regerssion whereby lines starting with eofmark but are not equal
to eofmark would be corrupted. This patch fixes it.
Test case:
cat << _ACEOF
_ASBOX
_ACEOF
Old result:
SASBOX
New result:
_ASBOX
