A test file with lots of small functions, or a big function with independent
parts that can be tracked by source location,
can use these directives to pretend it is the result of preprocessing lots of
#include directives for smaller files.
We would still need a dump option to tag the output with the filename. If this
takes the form of prepending each line with the filename, we can use standard
scan regexps to check the for presence or absence of pattern for a specific
part (rather than the current mess of expecting a total count).
