#5288 -o description in man page should offer FILE or FOLDER as in Usage manual

[Federico Bruni]

I'm not marking this as Documentation type, as the change should be done in the source file.
The manual page says that -o option will write output to FILE. It does not mention the possibility of saving to a different folder (if that name exists), as explained in Usage manual, chapter 1.2.

Here's the line to be changed:

$ git grep 'write output to FILE' lily/
lily/main.cc:183:  {_i ("FILE"), "output", 'o', _i ("write output to FILE (suffix will be added)")},

Mention FILE or FOLDER arg to -o command-line option.

As Federico explained in issue #5288, this is mentioned
in the Usage manual, but not in the man page/command-line help.
