[boost] Reading DOT files with Boost.Graph

So, I'm trying to read some dot files (that are generated by a tool 
looking at a perforce depot.
Most of the files "read_graphviz" just returns false. So, I started 
cutting down my test cases to see what's going on.

Here's what I found:

digraph G {
    a0 [ label = "//depot/path/to/file_1" ];
    a1 [ label = "//depot/path/to/file_2" ];

    a0 -> a1 [ color=gray ];
}

works great, but

digraph G {
    a0 [ label = "//depot/path/to/file_1#4" ];
    a1 [ label = "//depot/path/to/file_2#9" ];

    a0 -> a1 [ color=gray ];
}

fails. Apparently the DOT reader doesn't like "#"s in quoted strings. :-(

Any ideas on an easy way to fix this? I'm looking at the spirit 
grammar behind the parser
and it is less than totally straightforward.

Thanks in advance!
