New Revision: 73974
URL: http://svn.boost.org/trac/boost/changeset/73974

Log:
Quickbook: Better id generation for duplicates.

- Replaces repeated underscores with single underscores
- Truncates if they're too long.
- If the result ends with if a number, adds an underscore to separate
  that from the duplicate number.

Only doing this for the duplicate ids, so that the main generated id
doesn't change for existing documentation. Will do something similar for
all generated ids in quickbook 1.6.
