show notes about discarded mark/keyword expressions

[RonnyPfannschmidt]

as i keep both others and me making the mistake of thinking -k and -m compound/or (even though they replace)

i propose we show a note on discarded marker/keyword expressions in the header by default as it helps people to figure their mistake

in the header by default as it helps people to

That sentence is incomplete, might have hit "Send" too soon. 😁

@RonnyPfannschmidt / @nicoddemus is there a case for erroring if -k or -m is presented multiple times on the command line? (rather than tracking the initial values, using the latest and writing in the header to let the user know) ? I'll look into this one, im just wondering if we are overwriting anyway and always taking the latest if we should prevent -m foo -m bar initially? (not 100% on the edge cases here, so deferring to you)

@symonk this allows to override adopts based defaults

Im pretty sure it is in use, so we start with a warning, then gauge ux needs
