CHECKSTYLE suggestions: unnecessary quotations and unnecessary \f escape

[Alejandro Colomar (man-pages)]

Hi Branden,

While fixing style issues in the man-pages project,
I'm finding a few recurrent issues that I think you could warn about:

Unnecessary quotations:

[
.I "foo bar"
.IR foo "bar"
]

Unnecessary escape \f:

[
foo \fIbar\fP baz
]

The last one is more difficult to decide when it's unnecessary, but you
could maybe start with non-formatted lines.

Cheers,

Alex
