I do a find-grep, and it's great.  The buffer is compilation mode and
everything.  But I often want to do the same search again after doing
some editing.  Most of the time, for compilation mode, when I try again,
it would have the same compile command.  Not in find-grep.  In other
modes, a simple 'g' would redo it, but in the find-grep, it does
something else (It seems to me that it used to try to do a compile with
`make -k` but now it seems to want to save the buffer.)  A stackoverflow
user suggested filing a bug report
(
http://stackoverflow.com/questions/35808207/how-can-i-easily-repeat-emacs-find-grep
),
so here it is.
