Is there a reason that data is a void-pointer here and not a const char
*?

Only that it emulates `strbuf_add()`, which also uses a void pointer.

The reason for that is because strbuf is a generic byte-array which
may contain embedded NULs, and the `const void *` plus `len`
emphasizes this property, whereas `const char *` would imply a
C-string with no embedded NULs.

Thanks, that was the explanation I was missing. Perhaps it is worth
re-stating in the commit message here to avoid confusing readers like I
was when I first read Patrick's patch ;-).

Does it make sense to explicitly state how the interfaces look like
though? I don't do that for the other functions either, and for most of
the part I just reuse the exact same function arguments as we had with
the strbuf interface.
