We do not necessarily have to have these files immediately next to
the corresponding source file.

For example, we could give .shrapnel/ hierarchy to *.hco and *.sp
files, so that for revision.c and compat/bswap.h, we'd create
.shrapnel/revision.sp and .shrapnel/compat/bswap.hco files that will
not be so cluttering ;-)
