Description:
When using mysqldump with a "where" argument containing a newline, the exported SQL contains a comment with the WHERE clause used. The comment contains the newline and becomes invalid.

How to repeat:

mysqldump --options... --where="col1=val1 \
  AND col2=val2" databasename tablename > dump.sql

dump.sql will contain a line like this:

<pre>
--
-- Dumping data for table `tablename`
--
-- WHERE: col1=val1
  AND col2=val2

LOCK TABLES ...
</pre>

In this case, the line "  AND col2=val2" should be part of the comment but it's not.

Suggested fix:
Suppress newlines in the exported comment or add double dashes to every line.

I can't reproduce it myself. I guess you can close this bug. Sorry for the inconvenience.
