annotate PyOutputDescriptor.cpp @ 46:af9c4cee95a8

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
VC++ fixes. Much of this is changing "and" to "&&". I had never realised until today that "and" is in fact a keyword in C++, albeit not one that has been there since the start, so this should compile (I eventually looked this up having been puzzled by how this code could ever build with any other compiler). However, despite its keywordness, "and" still doesn't seem to be acceptable to VC++. Possibly there's an option to change this, or one could use a macro -- but why not just stick with the token that compilers are known to like?
