In some man pages, the usage synopsis is being cut short with later parameters lost. This is because the .BI macro can only take up to 6 arguments. (see http://www.linux.com/feature/34212\)
The solution is to use multiple .BI lines with a \c at the end of all but the last line to avoid adding extra spaces. This \c doesn't actually appear to work on Solaris but a spurious space (before a comma separator or the closing parenthesis) is a lot better than missing parameters.
I have attached a patch. It can perhaps be done more elegantly using exsl:node-set if you prefer.
