 time_input_facet doesn't support the %e substitution for days without
 leading zero.

 This means that the following code for parsing RFC 2822 dates fails:

 {{{
 auto time_facet = new boost::posix_time::time_input_facet;
 time_facet->format("%a, %e %b %Y %H:%M:%S");
 }}}

 Test strings (note that time zone portion is not parsed):

 {{{
 Tue, 15 Jan 2013 06:50:21 -0700
 Wed, 9 Jan 2013 12:33:57 -0700
 }}}

 Also note that the second date makes %a, %d %b %Y a non-starter.

 The attached patch fixes the problem for me.  The patch is against 1.51,
 but I check the 1.53 code and upon a brief code inspection it didn't
 appear to have changed significantly.

 Note that I made no attempt to verify how it behaves on badly constructed
 input; I simply cloned the %d code and changed it to call
 parse_var_day_of_month() instead of parse_day_of_month().
