buildozer can accept an argument for the set command with appropriately escaped newlines to force multiline values that would otherwise be written out as a single line. When buildozer reads commands from a commands file, it reads a single line and attempts to apply it as a command, so newlines can't be used to force a multiline value. To enable forcing multiline values when using a commands file, this updates buildozer to continue reading lines when a line ends with an escaped newline to match the behavior on the command line. This additionally adds a test case for using whitespace on the command-line so that there is consistent coverage for the two modes.

Code Review
This pull request aims to enable multiline commands in command files for buildozer, similar to how they are handled on the command line. The change involves modifying appendCommandsFromReader to read subsequent lines if a line ends with a continuation character (\). While the intention is good and new tests have been added, the implementation of the line continuation check in edit/buildozer.go appears to be incorrect and will not work as intended with the provided test cases.
