/**
* 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
