Re: nasty commit bug

I saw this same problem last night while setting up a new subversion
repository. "svn commit" was hanging on added files. After saving
changes and re-checking out, then checking new stuff in I discovered that
one file was corrupt. It appeared to be a mix in one section of several
different versions, and I lost the end of the file. Thankfully, using
subversion, I recovered the original file version and patched in the
missing parts.
