 add_c_file.py was added in commit 2f31c8146f in 0.4.1.2-alpha.

 But it has a bug: the suggested usage fails with:
 {{{
 $ scripts/maint/add_c_file.py ./src/feature/dirauth/ocelot.c
 Made files successfully but couldn't identify include.am for
 ./src/feature/dirauth/ocelot.c
 Exit 1
 }}}

 The correct usage has no "./":
 {{{
 $ scripts/maint/add_c_file.py src/feature/dirauth/ocelot.c
 }}}

 We should fix the usage, or make topdir_file() use python's canonical path
 functions.
