These handful of tests had a BOM (Byte order mark) at the beginning of the file. This marker is unnecessary in our test files. The main motivation for this is that the `ast` python module breaks when passing a file to it with a BOM marker (and might break other tooling which doesn't expect it). E.g.,: ``` """Test that lldb command 'process signal SIGUSR1' to send a signal to the inferior works.""" ^ SyntaxError: invalid non-printable character U+FEFF ``` If anyone is aware of a good reason to keep it, happy to drop this.
