Subject: init: plug tiny one-time memory leak
X-Git-Tag: v1.7.3.2~23
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=9173912be36c4f967f42f176be767fc5ba3c4077;p=git.git

init: plug tiny one-time memory leak

The buffer used to construct paths like ".git/objects/info" and
".git/objects/pack" is allocated on the heap and never freed.

So free it.  While at it, factor out the relevant code into its own
function and rename the sha1_dir variable to object_directory (to
match the change in everyday usage after the renaming of
SHA1_FILE_DIRECTORY in v0.99~603^2~7, 2005).

Noticed by valgrind while setting up tests (in test-lib).
