This changeset fixes bug 30190 "'bzr cat' requires full path in old revision".<br><br>``bzr cat`` can look up contents of removed or renamed files. If the<br>pathname is ambiguous, i.e. the files in the old and new trees have
<br>different id's, the user needs to use "--old" or "--new" to distinguish<br>between them. If the pathname refers to a single file, the options are<br>unnecessary.<br><br>Cheuksan Edward Wang<br>
