sflow module and increasing useragent

If I wanted to increase the amount of bytes logged by the sflow module
for the user agent to, say, 128 bytes, what would I need to change?

I tried changing this:

(in ngx_http_sflow.h)

but I still get the user agent truncated at 64 bytes. Nor does it seem
like SFLHTTP_MAX_USERAGENT_LEN is used anywhere in the code (or any
SFLHTTP_MAX_* define).

I'm sure I could whack on it long enough to get it to work, but I ask
mainly because I don't want to cause some buffer/format/etc overflow
somewhere else down the line. Thanks!
