Thanks for the report. It's not the less-than sign; it's the hash character
that makes the difference. The command-oriented history mode has to pay
attention to those, because shell comments are one place where you can't
replace a newline with a semicolon. It just needs to also pay attention to
the fact that bash is reading a here-document.

This was reported and fixed in October, 2019, and the fix is in the devel
branch.
