Description
Bug report
Bug description:
Code like this
str. \
format
should be coloured the same way as
str.format
Right now IDLE doesn't respect the slash before the newline and thinks that every new line is a new statement.
Similarly in:
x = match if match else \
match
The last match should be coloured in like a variable and not a keyword.

Research direction
Start in IDLE's syntax-highlighting behavior and reproduce the two examples involving a backslash before a newline. Verify that the continued expression is colored like the equivalent single-line expression, including the final match variable; linked PRs gh-140335 and gh-140337 show that work is already underway.
