Doc: clarify a wording

[Francisco Vila]

Hello,

I need to understand this (apparently unfinished) paragraph to be able
of translating it, thank you!

The default beam settings for the time signature can also be
changed, so that set the desired beaming will always be used
Changes in automatic beaming settings
for a time signature are described in @ref{Time signature}.
