Change to emacs.c: USAGE1 string is too big for Microsoft compiler.

[Stephen Powell <stephen_powell@optusnet.com.au>]

The latest update to emacs.c makes the USAGE1 string to long for
Microsofts compiler.  It doesn't like this line:

      printf (USAGE1, argv[0]);

| emacs.c(1067) : error C2026: string too big, trailing characters truncated
`----

According to Microsofts site
<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore/html/C2026.asp>

The string was longer than the limit of 2048 single-byte characters.

Prior to adjacent strings being concatenated, a string cannot be
longer than 2048 single-byte characters.

A Unicode string of about one half this length would also generate
this error.
