Hmmm, this is bug in the sense that it may cause confusion during
merges, but it is correct in the sense that the basic design of keyword
expansion specifically permits "freezing" an expanded keyword by
removing that entry in svn:keywords. Once you remove the entry from
svn:keywords, that keyword text is no longer considered special in any
way; it is now just a string of text. I cannot think offhand why this
would be /useful/, but there it is.

I think the appropriate fix is to add documentation emphasizing that if
you remove a keyword entry from svn:keywords, any existing expanded
keywords in the source files will not be unexpanded and that this could
cause problems with merging later.
