- * Return the current fileset based BufFile size.
+ * Returns the size if the given BufFile in bytes.

"Returns the size of", no doubt?

A shade less nit-pickily, I wonder if "size" is sufficient.
It's not really obvious that this means the amount of data
in the file, rather than say sizeof(BufFile). How about

+ * Returns the amount of data in the given BufFile, in bytes.

LGTM other than that point.
