* symfile.c (generic_load): Use buildargv() and tilde_expand() to parse file names with quoting, spaces and tildes properly. (load_command): Quote all special characters before calling target_load() such that buildargv() doesn't break file names. (_initialize_symfile): Mention the load offset in the help for the load command. * remote-sim.c: Include readline.h. (gdbsim_load): Use buildargv and tilde_expand() to parse file names with quoting, spaces and tildes properly. * target.h (target_load): Comment the parameters better. * Makefile.in (remote_sim.o): Add readline.h dependency. testsuite/ * gdb.base/help.exp (help load): Update expected results.
