Subject: autodetect number of CPUs by default when using threads
X-Git-Tag: v1.6.2-rc0~204^2~2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=43cc2b4266cc75f1a5a10e1a805d05e419000573;p=git.git

autodetect number of CPUs by default when using threads

... and display the actual number of threads used when locally
repacking.  A remote server still won't tell you how many threads it
uses during a fetch though.
