This changes find_and_open_script to return a gdb::optional<open_script>, where open_script is a new type encapsulating the two return values. The new type helps avoid cleanups in the callers. ChangeLog 2017-08-03 Tom Tromey <tom@tromey.com> * cli/cli-cmds.c (find_and_open_script): Change return type. Remove "streamp" and "full_path" parameters. (source_script_with_search): Update. * auto-load.c (source_script_file): Update. * cli/cli-cmds.h (find_and_open_script): Change type. (open_script): New struct.
