hghave: split apart testing for the curses module and `tic` executable
ef771d329961 skipped the check for the `tic` executable, because the curses
module alone on Windows is enough to pass the `test-*-curses.t` tests. However,
`test-status-color.t` uses this same check and explicitly invoked the
executable, which fails on Windows. From the cursory searching I did, curses on
unix requires `tic`, which I assume is why they were tied together in the first
place. So this continues to require both to get past the curses guards on non
Windows platforms.

$ hg init
$ echo a > a
$ hg ci -Ama
adding a
$ echo b > b
$ hg branch b
marked working directory as branch b
(branches are permanent and global, did you want a bookmark?)
$ hg ci -Amb
adding b
$ hg co -C 0
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
Fast-forward:
$ hg merge b
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
$ hg ci -Ammerge
Bogus fast-forward should fail:
$ hg merge b
abort: merging with a working directory ancestor has no effect

Even with strange revset (issue4465)
$ hg merge ::.
