[PATCH 5/6] shortlog: correct option help for -w

["René Scharfe" <l.s.r@web.de>]

Wrap the placeholders in the option help string for -w in pairs of
angular brackets to document that users need to replace them with actual
numbers.  Use the flag PARSE_OPT_LITERAL_ARGHELP to prevent parseopt
from adding another pair.
