BUG: doesn't detect manual dash-convention correctly

[carlbordum]

manly curl -sS should produce the same output as manly curl -s -S, but it doesnt:

$ manly curl -sS
No flags found.

$ manly curl -s -S 

curl - transfer a URL
=====================

      -S, --show-error
              When used with -s, --silent, it makes curl show an error message
              if it fails.

      -s, --silent
              Silent or quiet mode. Don't show progress meter  or  error  mes‐
              sages.   Makes  Curl mute. It will still output the data you ask
              for, potentially even to the terminal/stdout unless you redirect
              it.
