Now I understand what is your complaint. Yes, I agree that the
sentence produced by an @xref should begin with a capitalized "See".
Isn't that how they actually begin, in the Info file?
That is the bug: sentences stopped beginning that way in the default.
(Using today's CVS snapshot.) There are two reasons that I discovered
in emacs/lisp/info.el in `Info-fontify-node':
* First, the previous line of text, before a blank line, ended with a
colon. (You can see that here.) A colon followed by a blank line
should not force lower case when a blank line intervenes.
To fix, move the colon from the conditional that always produces a
lower case `see' and to the conditional that produces an upper
case `See' and add a colon to the conditional involving a blank
line.
* Second, the `Info-fontify-node' function used `looking-at' rather than
`looking-back' which meant never checking backwards.
To fix, replace `looking-at' with `looking-back'.
I think these two changes fix all the problems; but I do not use the
default except for tests and would appreciate your trying this
yourself. Thank you.
Here is the diff:

Here is an @@pxref (@pxref{Musings on fossil fuels}) in a sentence.
Here is a standalone xref within parentheses:
(@xref{Musings on fossil fuels}.)
Here is another @@xref, no parentheses; this ends with a colon and
is followed by a blank line:
@xref{Musings on fossil fuels}.
