Subject: log-tree: always use return value of strbuf_detach()
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/82f51af3452bb80e2347bb45dba3e1d2f10d0be7?hp=745f6812895b31c02b29bdfe4ae8e5498f776c26

log-tree: always use return value of strbuf_detach()

strbuf_detach() has been returning a pointer to a buffer even for empty
strbufs since 08ad56f3f0 ("strbuf: always return a non-NULL value from
strbuf_detach", 2012-10-18).  Use that feature in show_log() instead of
having it handle empty strbufs specially.
