Subject: gitweb: Make git_get_refs_list do work of git_get_references
X-Git-Tag: v1.4.3-rc1~72
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=120ddde2a843e923944abd5d6e61f8625e820e92;p=git.git

gitweb: Make git_get_refs_list do work of git_get_references

Make git_get_refs_list do also work of git_get_references, to avoid
calling git-peek-remote twice.  Change meaning of git_get_refs_list
meaning: it is now type, and not a full path, e.g. we now use
git_get_refs_list("heads") instead of former
git_get_refs_list("refs/heads").

Modify git_summary to use only one call to git_get_refs_list instead
of one call to git_get_references and two to git_get_refs_list.
