I'm not talking about grepping logs.  I'm talking about grepping code
once you have something in the logs.  With line breaks in the code but
not in the log, you will not get the desired result.

Example:


fprintf("This is a line ");
fprintf("broken in two code lines\n");


Output is:

This is a line broken in two code lines


Picking that line from the output and grepping for it in the source
doesn't get you what you want.
