* Export $NVM_DIR if it doesn't exist and use it when looking for nvm
* Use $NVM_DIR when looking for nvm for completion
* Use $NVM_DIR when looking for nvm in nvm_prompt_info
* Function wasn't returning correct value
* Updated underlying git command
* Kept echo command from previous function for backwards compatibility
* Kept function consistent with git_commits_behind
In places, the local statement will override the exit code and the written
command won't have the effect intended when it was written.
For example, when it's not inside a git repo the exit code won't be true,
but the local statement will make it true regardless. See #4708.
Fixes#4085: core -> plugin dependency issue.
Rename it to git_current_branch for clarity that it's git-specific.
Update all plugins that were calling it to use new name.
Fix variable leaks by making more variables in lib/git.zsh local.
Have lib/git.zsh use [[ ]] instead of [ ] everywhere.
Currently, the title is only set on supported terminals (i.e. xterm,
urxvt, screen etc.). Using terminfo entries to set the terminal title
adds support for many more terminals.
This change enables UP-arrow and DOWN-arrow full-line history completion.
For example, if you write `git clone` and press UP:
- Before this change,
it will use the last command that starts with `git`.
- After this change,
it will use the last command that starts with `git clone`.
Otherwise `start` will confuse the first parameter as the title of
a new command prompt if the parameter contains whitespace. That is
because the command to be run will be:
start "abc def"
which opens a new command prompt window with the title "abc def".
With the added empty string we force the start command to interpret
the passed parameter as the file / command:
start "" "abc def"
which will be interpreted like `""` is the title and the rest is
the file or command to start.
-------
**NOTE:** this wouldn't be necessary if the start script in msys
was defined differently; that is, if it had the empty string
already incorporated in the script (/usr/bin/start), like so:
```diff
-cmd //c start "${@//&/^&}"
+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.

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.
Uniform git prompt equal remote to all others prompts, setting the correct symbol
(if applicable) to $git_remote_status, instead of echoing it.
It also solves the problem pointed out in #3911
