Bash-completion

====================

====================

**Changed:**

None

* Use the command's basename instead of the absolute path (see https://github.com/xonsh/xonsh/issues/4104)

====================

**Fixed:**

* Fix completion which uses a subshell environment
* Fix for string index error in stripped prefix

====================

**Fixed:**

* bash_completions to include special characters in lprefix

Previously, glob expansion characters would not be included in lprefix for replacement

.. code-block:: sh

$ touch /tmp/abc
$ python
>>> from bash_completion import bash_completions
>>>
>>> def get_completions(line):
... split = line.split()
... if len(split) > 1 and not line.endswith(' '):
... prefix = split[-1]
... begidx = len(line.rsplit(prefix)[0])
... else:
... prefix = ''
... begidx = len(line)
... endidx = len(line)
... return bash_completions(prefix, line, begidx, endidx)
...
>>> get_completions('ls /tmp/a*')
({'/tmp/abc '}, 0)

Now, lprefix begins at the first special character:

.. code-block:: sh

$ python
>>> from bash_completion import bash_completions
>>>
>>> def get_completions(line):
... split = line.split()
... if len(split) > 1 and not line.endswith(' '):
... prefix = split[-1]
... begidx = len(line.rsplit(prefix)[0])
... else:
... prefix = ''
... begidx = len(line)
... endidx = len(line)
... return bash_completions(prefix, line, begidx, endidx)
...
>>> get_completions('ls /tmp/a*')
({'/tmp/abc '}, 7)

====================

**Fixed:**

* If there are no files to source, a ``set()`` will no longer be inserted
into the completion script.

====================

**Fixed:**

* Fixed issue with incorrect strip lengths for prefixes with quotes in them
* Fixed bash script to also consider leading double quotes and not just single
quotes
* `bash_completion` will not return negative prefix lengths for files that need
to be string-escaped (files/folders with spaces in name)
