if this is a problem, I'll modify my proposal: let the $template$ be
slightly customizable.
for example instead of replacing "$REV$" with "$REV: nnnn $" I'd like
svn to replace "// REV$" with "nnnn // REV: nnnn$"
(note that the ": nnnn" part is necessary to match the leftmost
"nnnn" in a second pass)

this will do, because I can write

#define VERSION // REV$

and svn will change to

#define VERSION 1234 // REV: 1234$

no :)
because I want finer granularity: in my project, each source file has
its own version number, as an integer (not as a string).
at the moment the only way to get this is:

1) every file X.h starts with
#include "version/X.txt"

(note that this is bad practice, since every file must know its own
name...)

the companion text files (which are not versioned) just state:
#define SVN_REV nnnn

2) before building, preprocess every file and generate all the
companion files parsing 'svn info' ...

but this procedure is going to cause BIG problems, since code CHECKED
OUT will build, but code EXPORTED from the repo will not!
so I'm firmly convinced this is an issue for svn.
furthermore, I don't see any practical use for keyword substitution
AS IS, except cosmetic (?) reasons (don't tell me that $REV: nnnn$ is
pleasant :)
