Subject: fetch.c: do not call process_tree() from process_tree().
X-Git-Tag: v1.4.0-rc1~10^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=6f9012b62517ca490e4131f24e03ff842527f1b9;p=git.git

fetch.c: do not call process_tree() from process_tree().

This function reads a freshly fetched tree object, and schedules
the objects pointed by it for further fetching, so doing
lookup_tree() and process_tree() recursively from there does not
make much sense.  We need to use process() on it to make sure we
fetch it first, and leave the recursive processing to later
stages.
