  • mto: This revision was merged to the branch mainline in revision 1797.
  • Revision ID: mbp@sourcefrog.net-20060615053634-4fd52ba691855659
Clean up many exception classes.

Errors indicating a user error are now shown with is_user_error on the
exception; use this rather than hardcoding a list of exceptions that should be
handled this way.

Exceptions now inherit from BzrNewException where possible to use consistent
formatting method.

Remove rather obsolete docstring test on Branch.missing_revisions.

Remove dead code from find_merge_base.
