The issue with this suggestion is that the prototype of
percent_color_snprintf() is:

  int percent_color_snprintf(char *bf, size_t size, const char *fmt, ...)

So, I can only pass value_color_snprintf() a va_list, making its prototype:

  int value_color_snprintf(char *bf, size_t size, const char *fmt, va_list args)

Is this worth the minor rename?

On a related note, does percent_color_snprintf() need to be a variadic
function? It only seems to process one percent value.
