+- file names and contents for all relevant source files are displayed.\n\
+\n\
With a /r modifier, raw instructions in hex are included.\n\

With a single argument, the function surrounding that address is dumped.\n\
Two arguments (separated by a comma) are taken as a range of memory to dump,\n\

you must type \"disassemble 'foo.c'::bar\" and not \"disassemble foo.c:bar\"."));
