Subject: log: add load_ref_decorations()
X-Git-Tag: v1.6.1-rc1~231^2~2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=5e9bf11c1a3052f01f86d7eb28ae4c5b8d9c7495;p=git.git

log: add load_ref_decorations()

Move the loading of all ref names for decoration into its own function.
A static variable prevents loading twice, because it's quite expensive.
We can do it this way because we currently never unload decorations.
