[PATCH] branch: reset instead of release a strbuf

[Stefan Beller <sbeller@google.com>]

Our documentation advises to not re-use a strbuf, after strbuf_release
has been called on it. Use the proper reset instead.

Maybe one of the #leftoverbits is to remove the re-init call in release
and see what breaks? (And then fixing up more of such cases as presented
in this patch)

Thanks,
Stefan
