If features A and B are incompatible and both can be specified from
both command line and configuration, ideally I would expect the
system to operate in one of two ways. I haven't thought it through
to decide which one I prefer between the two.
* Take "command line trumps configuration" one step further, so
that A that is configured but not asked for from the command
line is defeated by B that is asked for from the command line.
This way, only when A and B are both requested via the
configuration, of via the command line, we'd fail the operation
by saying A and B are incompatible. Otherwise, the one that is
configured but overridden is turned off (either silently or with
a warning).
* Declare "command line trumps configuration" is only among the
same feature. Regardless of how features A and B that are
incompatible are requested, the command will error out, citing
incompatibility. It would be very nice if the warning mentioned
where the requests for features A and B came from (e.g. "You
asked for -B from the command line, but you have A configured,
and both cannot be active at the same time---disable A from the
command line, or do not ask for B")
When A is configured and B is requested from the command line,
the command will error out, and the user must defeat A from the
command line before the user can use B, e.g. "git cmd --no-A -B".
A knee-jerk reaction to the situation is that the latter feels
somewhat safer than the former, but when I imagine the actual end
user who saw the error message, especially the suggested solution
"disable A from the command line or do not ask for B from the
command line", may say "well, I asked for B for this invocation
explicitly with -B from the command line, and you(Git) should be
able to make it imply --no-A", which amounts to the same thing as
the former choice.
