The electric behavior of sh-electric-here-document-mode (activated by

default) is annoying when someone does not want to insert a

here-document. For example, the here-string syntax requires to insert

<<<, but the second insertion will trigger the here-document.

Steps taken:

- activate `shell-script-mode`

- enter the following text:

       read line <<< "Line of text"

Expected result: the buffer contains

       read line <<< "Line of text"

Actual result: the buffer contains

       read line <<EOF

       < "Line of text"

       EOF

Solutions are also discussed there, for example tweaking the trigger so that you need more than just '< <' to insert the here-doc.
