Re: keyword expansion for MS Office files

This feature can most likely not be implemented reliably in MS Office
binary formats. The issue is the actual office format itself.
Basically, Office doesn't store all of the text in one place, so it is
possible for a single string to be split with binary formatting
content. In most simple tests, this won't happen, but in files that
are actually edited, it can and will at some time. I have seen
strings in Office files that were split into two different substrings
with the exact same formatting. This happens when formatting is
accidentally applied to a portion of the string, and then it is
removed.

So, the easy answer is that in your tests, this will work, but it
won't ever be reliable unless svn grows to learn the office formats
(which shouldn't happen).

Putting the keywords into Office properties might be a different story.
