According to POSIX, "<<" and "<<-" are distinct shell operators. For the latter to be recognized, no whitespace is allowed before the "-", though whitespace is allowed after the operator. However, the chainlint patterns which identify here-docs are both too loose and too tight, incorrectly allowing whitespace between "<<" and "-" but disallowing it between "-" and the here-doc tag. Fix the patterns to better match POSIX. Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> --- t/chainlint.sed | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
