feedback: show a relevant message for M-O when the syntax has 'tabgives'

When the syntax contains a 'tabgives' command, toggling the conversion
of tabs-to-spaces has no effect -- not for the current file.  So, tell
the user that and don't change the flag.

This fixes https://savannah.gnu.org/bugs/?61496.

Bug existed since version 4.5, since 'tabgives' was introduced.
