+# Set the name of the end-user facing command in the reflog when the

+# another scripted Porcelain (e.g. "git am") and a call to this

+# GIT_REFLOG_ACTION when calling a "git" command to record a custom
+# reflog message, do not leave that custom value in GIT_REFLOG_ACTION,
+# after you are done. Other callers of "git" commands that rely on
