This looks like a lot more work than igrep.  I didn't have to select files 
and manually
enter the extensions.  igrep just knew that, if the file was c-mode, it 
should search
*.[ch] *.cpp --- by default.

In combination for "search for the string under point", I could grep with 
a single keystroke.
