[cfe-dev] Info diagnostic level

[Victor Zverovich]

The name Remarks is OK for me.
I see one of the uses of this in for the output of progress information, for
example, to report which file is being compiled as VS does. However it can
be seen as a general output facility that uses diagnostic instead of writing
to the stdout.
Therefore I think that this kind of diagnostic unlike errors, warnings or
notes should be output by existing clients with minimal
formatting (without prepending "remark: " or whatever, only the location if
it is specified).
For the same reason I'd say that it shouldn't be counted in the diagnostic
count and should be never turned into
errors with -Werror.
Does it make sense?
