Summary: format_paragraph in options_description.cpp

Initial Comment:
function format_paragraph 
in options_description.cpp triggered assertion
_SCL_SECURE_VALIDATE_RANGE failure in microsoft vc8.

at line #379, it looks for a space backword to
avoid chopping a word in the middle. the expression
line_begin - 1 causes assertion failure
if line_begin is at the beginning of the description
string.

here is suggested fix
