I believe that we should always have code of the form:

    assert(!blah);
    if (blah)
      {
        /* do some reasonable thing */
      }

In some cases, that would manifest itself as:

    assert(x);
    if (!x)
      return svn_error_create(...);

In some cases, that would manifest itself as:

    assert(x);
    if (!x)
      abort();

Because the assertion generates such rich error messages,
it should be favored over abort(), but the abort() should
not be discarded when there is no reasonable way to proceed.
