Change option '-m' to '-M' for consistency of cli

`-m` was added as short option for `--no-mouse`, this is inconsistence
to the rest of the cli since otherwise the short options to disable a
feature are capital letters. Therefore this commit renames the option to
`-M`.

This commit also documents the option in the man page.
