Subject: prune-packed: use strbuf to avoid having to worry about PATH_MAX
X-Git-Tag: v1.9-rc0~39^2~1
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/c235d960cb32ddca352d12c3f8dc053ddfd421dd?hp=c235d960cb32ddca352d12c3f8dc053ddfd421dd

prune-packed: use strbuf to avoid having to worry about PATH_MAX

A/very/long/path/to/.git that becomes exactly PATH_MAX bytes long
after suffixed with /objects/??/??38-hex??, would have overflown
the on-stack pathname[] buffer.
