I'd probably get just as annoyed seeing that message repeatedly as I
would seeing the "(each doohickey is reported only once for each flurble)"
message that started this subthread.  :-)

This is one of those few areas where I feel the compiler should take
parameters from an environment variable.  Maybe leave "beginner mode"
messages on by default, but allow others of us to set

    export GCC_DIAGNOSTICS=nobeginner,spaced_out,ANSI_color_highlights

to turn off the extra messages, and also do indenting like

with colors, etc.

Maybe only the driver would check for environment variables, and then insert
the appropriate -fdiagnostic options into the command line for the compiler.
