The matrix math will not always invert, although if the matrix
is a pure rotation  (with no scaling or shears) the transpose
of the matrix is the inverse.
A better solution would be for the inliner to apply a start
and a stop tag for each inlined file. Perhaps "0 INLINE START "
followed by some pseudo-random string (like mime-enclosures, if you've
ever seen them in-the-raw). Surround the inlined file with
identical tags and have the first line be the commented-out
original.  In this way, the inlining operation would be completely
reversable.

Is there any way to reverse the inlining to the original file (lossless
outlining, I guess it would be) using the comment that the inlining function
writes?  Does the matrix math work in this direction?

(...) Adding a closing tag (and unique ID) is a good idea, and something that should have been done from the start. It would solve the problem of identifying the chunk of code to reverse out, and restoring the original referencing file would be (...)
