Subject: Cleanup duplicate initialization code in transport_get
X-Git-Tag: v1.5.4-rc0~292^2~48
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=8eb554ae628d2504922912fb5f046741da4654fc;p=git.git

Cleanup duplicate initialization code in transport_get

We always allocate and return a struct transport* right now as every
URL is considered to be a native Git transport if it is not rsync,
http/https/ftp or a bundle.  So we can simplify the initialization
of a new transport object by performing one xcalloc call and filling
in only the attributes required.
