[Module::Build] ./Build dist - files not added which aren't enlisted in MANIFEST?

[Steven S. <sch...@cp...>]

As I was in the process of adding a freshly created testfile to 
the subdirectory t/ of a distribution I got biten when I ran 
the dist action because it was my natural assumption that the new 
file would be implicitly integrated - but it wasn't.

So I had to rerun the manifest action on it to have it included.

Is this intentional behaviour? If not, shouldn't we emit a warning
for all files which aren't currently included and are not subject 
to exclusion by MANIFEST.SKIP when running the dist action?
