Subject: Make << shell heredoc expansion less enthusiastic
X-Git-Tag: emacs-27.0.90~1146
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=8e4a090ff71f64b1d36aebc3f6a8e0145f690bf9;p=emacs.git

Make << shell heredoc expansion less enthusiastic

* lisp/progmodes/sh-script.el (sh--maybe-here-document): Require a
space before expanding a heredoc (bug#3226).  This allows the user
to insert a bash <<< "herestring", which was previously difficult.
