If "repo init" was run in a path containing "%", "repo info" would fail
printing the path with
File ".repo/repo/color.py", line 173, in f
return fmt % args
TypeError: not enough arguments for format string
as the "%" in the path name is interpreted as the start of a formatting
specifier. Avoid that by using the non-formatting printer for headtext
which does not require any formatting so there is no need to try to
expand "%" sequences.
