Subject: worktree.c: rewrite mark_current_worktree() to avoid strbuf
X-Git-Tag: v2.10.0-rc0~160^2~4
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=360af2dadaae70f29de2f21d4eb8ac38aefcc263;p=thirdparty%2Fgit.git

worktree.c: rewrite mark_current_worktree() to avoid strbuf

strbuf is a bit overkill for this function. What we need is to call
absolute_path() twice and make sure the second call does not destroy the
result of the first. One buffer allocation is enough.
