[Lldb-commits] [PATCH] D52270: TestMultilineExpr: validate evaluation for expressions spread over multiple lines

[Stefan Gränitz via Phabricator via lldb-commits]

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.
