Although "-vo" and "lint usual arguments ?" are useful, they produce a lot of information, including information that sometimes could be considered 'what was noise' such as temporary error suppressions "-save, -e123, -restore"

It would be great if you could add a feature where I could display all options, suppressions, flags, etc. in effect at a specific point in a source file that have been:
a) changed from the defaults, or
b) changed since the last "-save"
c) changed in this file

for example:
//lint -save
//lint -e123
//lint -esym(456, FooBar)
...
/lint -save -e789 */ MACRO /lint -restore */
...
int foo()
{
//lint -ListOptions(save)
}
would tell me about -e123 and -esym(456, FooBar) but not -e456
