Thanks for explaining it more clearly.

Having another word for "disassembly" seems clumsy though. ["apropos
opcodes" doesn't print anything today]
Plus to a new user the intent of the option is a bit vague.
"disassemble-next-line" ? [that has a lot to type to become
unambiguous, but it's not something the user would presumably type
often, if not in .gdbinit or some such]

Also, the user might want to set a limit on the number of lines of
disassembly displayed.
If cut short gdb could print "[output cut short due to `set
dissemble-next-line-max 10']" (or some such).

For debugging optimized code, maybe it'd be nice if gdb determined
there were more (discontiguous) lines of disassembly to display for
the current source line and notified the user (by printing
"discontiguous source line" or some such) before and/or after the
output.
