I see nothing wrong in the proposed log message nor in the patch
text.  Nicely done.

Having said that, we could be a little bit more ambitious and make
this into a two-patch series, i.e.,

 [1/2] does this exact change + "grep -> test_grep"
 [2/2] modernises the style to remove blank lines at both ends of
       each test
