It is occasionally useful to be able to build strings with embedded 0X
characters. In Win32 lists of strings are often represented using 0X as a
separator. An additional 0X terminates the entire list.

For example, to define a list of filters for a file requester dialog, one
specifies a string that contains a list of pairs of strings. In C, the
strings can be easily separated by embedded 0X characters:

  "Oberon-2 Files\0*.mod\0LaTeX Files\0*.tex;*.bib\0"

Admittedly, this is an unusual use of string constants and I wouldn't be
too concerned about it. Otherwise, the string concatenation looks fine to me.
