/**
 * This method was introduced to fix defect #26964.  For Java 1.0.2
 * on Win NT, the escape sequence \u0020 was not being handled
 * correctly by the Java Properties class when it was the final
 * character of a line.  Instead the trailing blank was dropped
 * and the next line was swallowed as a continuation.  To work
 * around the problem, we introduced our own metasymbol to represent
 * a trailing blank.  Hence:
 *
 * Performs substitution for any metasymbols in the message
 * templates.  So far only %B is needed.  This was introduced
 * to make it more convenient for .properties files to
 * contain message templates with leading or trailing blanks
 * (although %B may actually occur anywhere in a template).
 * Subsequently, checking for '\n' has also been added.  Now,
 * wherever '\n' occurs in a message template, it is replaced
 * with the value of System.getProperty ("line.separator").
