Replaces #596. Differences:
- Tests and metavar.
- Uses “jobnum” name in place of “jobs”.
- Does not use subshell for zsh. Also counts jobs correctly in zsh.
- Adds an option to force showing jobnum segment even if there are no jobs.
Some notes on the commit:
1. As external_ip and email_imap_alert segments seem to be removed corresponding
segment_data keys also were removed.
2. Various files that import vim module now have the usual workaround that sets
vim local to dummy object on error.
3. Syntastic check was failing because it did not specify which highlighting
groups it uses in documentation. I made it specify them and also moved format
strings to keywords. Same for some other plugin-local themes.
4. powerline-lint script got --debug argument. Pretty useless currently though:
it only makes it output traceback for ImportError when failing to import
module to stderr.
5. Moved themes/vim/plugin/*.json to themes/vim/plugin_*.json.
6. Fixed powerline-lint that ignored problems from values.
Use a .gitattributes file to tell git to not highlight trailing
whitespace as an error in .rst files when showing diffs. A trailing
space is used on many lines in those files to indicate that the
paragraph continues onto the next line.
If the g:powerline_no_python_error variable is set don't issue an error
message even if vim doesn't have the required Python support. This
allows a common set of configuration files to be used across systems
where some of the copies of vim don't meet the requirements.
This hacks around the way CtrlP handles statuslines. Powerline will
always override the statusline, but CtrlP doesn't make its details
available as buffer variables so separate functions assign the details
to buffer variables each statusline redraw.
Currently this statusline only uses a couple of highlight groups,
colorschemes should add the HL groups to make this prettier.
