This changes inferior.c to add Usage lines for all commands, and to change how "metasyntactic variables" are written to conform to GNU style. While doing this I noticed that the manual doesn't document the argument to "info inferiors", so I've added that as well. ChangeLog 2018-04-27 Tom Tromey <tom@tromey.com> * inferior.c (initialize_inferiors): Update help strings. doc/ChangeLog 2018-04-27 Tom Tromey <tom@tromey.com> * gdb.texinfo (Inferiors and Programs): Document argument to "info inferiors".
