This is how it does now, as far I have seen from the code (for warnings).

My motivation was the following:
1) Keep overall *number* of errors/warnings issued by bison reasonable. When
bison issues an "ambiguity" error with 10 sub-messages, overall number of
errors (if one does "grep" on output, or, alternatively bison itself will
count them and print a summary message) should be one.
2) Not to see the "warning" word in each sub-message.
