I don't know about "more general". However, I know very well that 
there's a particular project (Maven Release Plugin), which has this very 
problem with svn, not with awk, sed, or whatever. And I'd like to
fix that specific problem, not eliminate hunger in the world, or do 
whatever more general. To achieve that, I've pointed out a non-intrusive 
and harmless change in CygWin SVN, which might help to resolve that problem.

And, besides, your proposed solution won't work: I could, of course,
use "which", or "where" to deduce the location of "svn", but what would
that tell me. Assuming, I get "/usr/bin/svn", then I'd know that "which"
is a CygWin binary (because it emits a CygWin path), but what's got that
to do with svn? The fact that it resides in the CygWin bin directory
doesn't mean it is also a CygWin binary.
