config: give it an includepaths option for looking for config files
It is desirable to "derive" templates from the provided templates. A
simple way to do this is e.g.
%include map-cmdline.default
in your own mapfile. Then you only have to redefine a few templates
instead of copying over the whole thing. This %include mechanism
already works for the built-in templates because by default it *only*
looks for files that are in the same directory as the including
mapfile.
With this changeset, config grows an option to add more include paths
for config files.
$ hg init
$ echo a > a
$ hg add a
$ hg commit -m test
Do we ever miss a sub-second change?:
$ for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; do
> hg co -qC 0
> echo b > a
> hg st
> done
