Subject: Introduce is_bare_repository() and core.bare configuration variable
X-Git-Tag: v1.5.0-rc1~3^2~2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=7d1864ce67d83485cf5cbc8c90fc170ee884ef16;p=git.git

Introduce is_bare_repository() and core.bare configuration variable

This removes the old is_bare_git_dir(const char *) to ask if a
directory, if it is a GIT_DIR, is a bare repository, and
replaces it with is_bare_repository(void *).  The function looks
at core.bare configuration variable if exists but uses the old
heuristics: if it is ".git" or ends with "/.git", then it does
not look like a bare repository, otherwise it does.
