Otherwise `start` will confuse the first parameter as the title of
a new command prompt if the parameter contains whitespace. That is
because the command to be run will be:
start "abc def"
which opens a new command prompt window with the title "abc def".
With the added empty string we force the start command to interpret
the passed parameter as the file / command:
start "" "abc def"
which will be interpreted like `""` is the title and the rest is
the file or command to start.
-------
**NOTE:** this wouldn't be necessary if the start script in msys
was defined differently; that is, if it had the empty string
already incorporated in the script (/usr/bin/start), like so:
```diff
-cmd //c start "${@//&/^&}"
+cmd //c start "" "${@//&/^&}"
```
Notice however that this would make it impossible to use start
setting a different title, so it's probably best to leave it as is.

The change `${(z)open_cmd}` is necessary to force zsh to split the
variable by the spaces and interpret it as separate words.

The old implementation would attempt to load both the default and custom
implementations, with the custom one coming first, so it would get clobbered
by the default version.
Apparently `nohup` is not needed in OSX, and using it has the side
that it may break under tmux with the error
nohup: can't detach from console: No such file or directory
For now, this commit only drops the use of `nohup` in OSX. But it
*may* not be necessary under other similar platforms.
Rather than trying to emulate `git commit --amend` using mercurial queues (which might have side effects if you're using MQ for other things) use the `commit --amend` command which was introduced in Mercurial 2.2 (2012-05-01).
The zle-line-init and zle-line-finish definitions here were broken with
respect to smkx/rmkx because their "if" logic had fallthrough where it shouldn't,
so the mode was left in rmkx all the time. This just removes those widgets
entirely, because they're now defined (correctly) in lib/keybindings.zsh and
not needed in plugins.
