This is one of the common exceptions though:

    $ git grep 'const char \* const' | wc -l
    186
    $ git grep 'const char \*const' | wc -l
    108

So when there is another keyword following the asterisk we tend to have
an additional space inbetween. We tend to only drop the space when the
next token is the variable name.
