+# The tree page browses a repository at one revision, either as a listing of a
+# directory or as a single file with an anchor on every line. The checks
+# against the repository named foo+bar cover a file name and a branch name
+# that both contain a plus, which cgit has to spell one way inside a path and
+# another way inside a query.
