Title: Use \- as minus in manpage

From [0]

By default, "-" chars are interpreted as hyphens (U+2010) by groff,
not as minus signs (U+002D). Since options to programs use minus
signs (U+002D), this means for example in UTF-8 locales that you
cannot cut and paste options, nor search for them easily.

So "\-" shall be used when minus is needed.
