Although the compiler wasn't complaining (since it was the pointer,
rather than what was being pointed to, that was actually const), it
looks quite suspicious to call a function with an argument labeled
const when the nature of the pointer (virBufferPtr) is hidden behind
a typedef. Dropping const makes the function declarations easier
to read.

Maybe a typo here?The virBufferPtr still remains const, but the
declaration of this function in the buf.h shows this const is
removed, too.
No. Rather, this is an artifact of git diff. When showing the
context line for a hunk, it uses the context from the pre-patch file
(where the 'const' was still present), even though the hunk itself
applies to the post-patch version without 'const'. Basically, I never
worry about the @@ lines - they are there as hints for where to apply
the patch, and not a definitive part of the patch itself.
Okay, forget the context line.
What I wanted to say is that the function virBufferAdd in the buf.c
still has the const before the virBufferPtr while the declaration of
this function in buf.h has const removed, after applying this patch.
