[gardening] When using C style comments, stick to the one line form.

In the rare cases where C style comments are needed sticking with the
one line form is preferred to allow for quick comment analysis by
simple methods such as:

$ git grep -E '(//|/\*.*\*/)'

When using the single line form the command above is guaranteed to
include all comment content (+ some non-comment content), which
greatly simplifies quick comment analysis.
