[cfe-dev] -ferror-limit omits part of last error message

[Bjorn Reese]

Consider the following program:

   class Alpha {};
   class Alpha {};

When compiled it will give the following reply:

<output>
   error-limit.cpp:2:7: error: redefinition of 'Alpha'
   class Alpha {};
         ^
   error-limit.cpp:1:7: note: previous definition is here
   class Alpha {};
         ^
   1 error generated.
</output>

The first messages tells us the error, and the second message contains
additional information about the error.

However, when compiled with -ferror-limit=1 we get:

<output>
   error-limit.cpp:2:7: error: redefinition of 'Alpha'
   class Alpha {};
         ^
   fatal error: too many errors emitted, stopping now [-ferror-limit=]

   2 errors generated.
</output>

The additional information about the (first) error is gone.
