I think I've found what's required:
In particular

If you want the file contents to remain unchanged you can always
change one of the properties on the file.


svn propset dummyproperty 1 yourfile

hence "Use Case: A file (config, xml, etc.) is chosen as a canonical
version beacon for other apps. It indicates that "the code queried
represents version rXYZ in SVN". Using SVN's macros on commit ("$Rev:
xxxxx $") would be ideal for these purposes, provided SVN would deign
to update an unchanged file. – pcorcoran"

So I can now force a change to each Info.plist file and embed the Rev
property.  I can also embed the Rev property in relevant .c or .h
files to cause the Rev property to show in the relevant VM version

And I can fire off the svn propset via a precommit hook.  What I can't
do is make this corss-platform.  It'll work on unixes but fall flat on
e.g. Windows wirth TortoiseSVN.  Unless anyone knows better.  If so,
let me know.

> While I'm in nitpicking mode: CFBundleVersion is recommended to be a simple integer, incremented for each bundle release - your "2459" might serve fine. This is not shown in the UI. The Finder shows CFBundleShortVersionString and the Get Info dialog shows CFBundleGetInfoString. Both of these are free-form as far as OS X is concerned, you can put anything you want in there. "Smalltalk vmVersion" includes CFBundleShortVersionString so there may be users expecting a certain format.
