The other repository, "repoB" is our portable version of the code---the one which is used to deploy on systems other than the one which repoA is deployed on.  As such, "repoB" often (and does) contain commits specific to repoB which will never appear in repoA, such as OS-specific things.

Why don't you name it foo.1.in in both repos and pipe it through "cat"
on repoA (i.e., just copy it to foo.1)?  Then you would only have to
maintain a small difference in your build system between repoA/repoB
rather than having to coordinate two versions of the bigger source document.
