Is this possibly just a stylistic issue?  Having the following
blank line as part of the concatenation sequence means that
values can be added or removed without the need to also modify
the adjacent line.  This might be particularly helpful if the
file is ever to be modified by an admin script.

I often see this done in makefiles when setting a macro to a
long list of values. (E.g., a list of source files.)
