 Maybe I'm missing something, but how does this fix the bug if
 some exceptions are rethrown?
 
 Also, what's the rationale behind rethrowing some but not all
 exceptions?
 
 I don't think that basic_filebuf should catch exceptions thrown
 by use_facet or codecvt members. It is clear from 27.6.2.1 etc.
 that streambuf members may throw; if underflow() fails because
 an exception is thrown badbit, not eofbit, should be set in
 rdstate(); and if badbit is set in exceptions() the original
 exception should be rethrown.
