bufSize of glGetInternalformativ does not follow spec

In the specification section 22.3 Internal Format Queries
(glspec46.core.pdf page 564), it is written:
No more than bufSize integers will be written into params.

The confusion may come from the man page where in one point it is said:
"No more than bufSize basic machine units will be written to this
memory." But the above description is still a number of integers.
