Summary:
When LLDB successfully parses a command (like "expression" in this case) and determines incomplete input, the user can continue typing on multiple lines (in this case "2+3"). This should provide the correct result.
Note that LLDB reverts input from the additional lines, so they are not present in the output.

Summary:
I have found a way to segfault lldb in 7 keystrokes! Steps to reproduce:
1) Launch lldb
2) Type `print` and hit enter. lldb will now prompt you to type a list of
expressions, followed by an empty line.
3) Hit enter, indicating the end of your input.
4) Segfault!
After some investigation, I've found the issue in Host/common/Editline.cpp.
Editline::MoveCursor() relies on m_input_lines not being empty when the `to`
argument is CursorPosition::BlockEnd. This scenario, as far as I can tell,
occurs in one specific instance: In Editline::EndOrAddLineCommand() when the
list of lines being processed contains exactly one string (""). Meeting this
condition is fairly simple, I have posted steps to reproduce above.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.
