The 2.6 sentence that got deleted in 3.0:

I at least somewhat agree.

"When compiling a string with multi-line statements, two caveats apply:
line endings must be represented by a single newline character ('\n'),
and the input must be terminated by at least one newline character."

could have "two caveats apply" deleted to be more positive.  I would
prefer the following simpler, direct use instruction.

"When compiling a string with multi-line statements, terminate all lines
with a single newline character ('\n')."

This issue came up both in c.l.p discussion and again in invalid #4262
(whose author apparently missed the current sentence).
