cmdutil: use crecordmod.checkcurses
Instead of blindly trusting the user's experimental.crecord, we use checkcurses
to abstract that logic so that we can handle the case where python was not
built with curses.
This test file aims at test topological iteration and the various configuration it can has.
$ cat >> $HGRCPATH << EOF
> [ui]
> logtemplate={rev}\n
> EOF
On this simple example, all topological branch are displayed in turn until we
can finally display 0. this implies skipping from 8 to 3 and coming back to 7
later.
