[Rivet] histogram legend with spaces and other characters

[Andy Buckley]

I know why... it's LaTeX so you need to escape % signs as \% otherwise 
you start a comment in the intermediate source file. I guess your 
command is creating a comment that breaks some matching of begin/end 
block commands and hence latex hangs (even though we're running it in 
non-interactive mode).

Not sure if we can (or should) protect against that! But it would be 
nice to fail more helpfully than hanging...
