Currently you can't make a conditional custom segment. This changes the
prompt_custom function responsible for printing custom segments so that
it won't print the segment in case the content is empty.
With this it becomes possible to make conditional custom prompts simply
by making it not print anything when it's not supposed to be shown.
`git rev-parse --git-dir` returns just `.` when in the top level of
a`.git` directory. This would cause a problem when extracting the
package_path. Closes#271
This ensures that the following package.json extract would just give the
prompt "foo" rather than "foo\nbar".
{
"name": "foo",
"author":
{
"name": "bar",
}
}
This commit provides a new segment `pyenv` to show current python environment.
This prompt can be used in place of `virtualenv` segment. However, it is
targeted at users of [pyenv](https://github.com/yyuu/pyenv) and not meant to
replace the `virtualenv` segment.
The prompt works by parsing output of `pyenv version` and displaying the first
word of the output as segment text. The design (color etc.) is same as the
`virtualenv` segment including the icon. The segment would need to be
revisited if `pyenv version` changes its output format.
Tested on my personal machines (Mac OSX 10.11.4 and Ubuntu 15.04).

Now it is possible to set the installation path by setting
POWERLEVEL9K_INSTALLATION_PATH. If set, this path will always be used.
If it was not set manually, we try to determine the path automatically.
The segment relies on a lookaround to determine the currently
active conda environment.
If available ack is preferred, otherwise grep will be used.
Recent versions of grep offer `-P` to support perl-regex.
Older ones (e.g. those shipped on OSX) will fail.
