Hi,
AFAIS it's inside
(defconst sh-here-doc-open-re
(concat "<<-?\\s-*\\\\?\\(\\(?:['\"][^'\"]+['\"]\\|\\sw\\)+\\)"
sh-escaped-line-re "\\(\n\\)"))
If you say, `sh-here-doc-open-re' must start at bol or
only permit whitespace before, inserting a ^[ \t]* into
the regexp
(setq sh-here-doc-open-re
(concat "^[ \t]*<<-?\\s-*\\\\?\\(\\(?:['\"][^'\"]+['\"]\\|\\sw\\)+\\)"
sh-escaped-line-re "\\(\n\\)"))
it works here.
HTH
