(line_completion_function): If we are completing on locations, back up the start of word pointer past all characters which can appear in a location spec. (location_completer): New function. * completer.h: Add prototype for location_completer. * symtab.c (make_source_files_completion_list) (add_filename_to_list, not_interesting_fname): New functions. (filename_seen): New function, body extracted from output_source_filename. (output_source_filename): Call filename_seen to check if the file was already printed. (make_symbol_completion_list): If TEXT includes a double-quoted string, return an empty list, not NULL. (make_file_symbol_completion_list): New function, similar to make_symbol_completion_list but with an additional argument SRCFILE. * symtab.h (make_file_symbol_completion_list) (make_source_files_completion_list): Add prototypes. * breakpoint.c (_initialize_breakpoint): Make location_completer be the completion function for all commands which set breakpoints and watchpoints. (top-level): #include "completer.h". * tracepoint.c (_initialize_tracepoint): Make location_completer be the completion function for the "trace" command. (top-level): #include "completer.h". * printcmd.c (_initialize_printcmd): Make location_completer be the completion function for the "print", "inspect", "call", and "disassemble" commands. (top-level): #include "completer.h". * infcmd.c (_initialize_infcmd): Make location_completer be the completion function for the "go", "jump", and "until" commands.
