There is no valid answer to this prompt, because those source files
simply aren't installed on the machine (at least for 99.99% of the
users, I expect).

I never considered doping what Paul suggests, because I expected the
amount of space wasted this way is too large.  But admittedly, once
compressed with something like lzip the C source files take up less
than 3MB, so it's really not that bad given the size of the `emacs`
executable, plus the .pdmp file and all the .elcs.

In the case of Debian, it would make sense to include those compressed-C
files in the `emacs-el` package (the optional package that provides the
(compressed) .el files, since a normal install of the `emacs` package
only installs the .elc files) which currently weighs in at around 16MB.

Arguably, this is something that Debian/RedHat should be doing on their
side, but maybe Paul's patch is an easier way to convince "all" distros
to do that, rather than lobbying them one by one.
