The parsing output for full git log output too slow so it replaced
with last commit show request, wich cause error if repository is empty

* muse theme: Remove a extra space for none git prompt

* muse theme: Remove a extra space for none virtualenv prompt

adding python virtualenv support to muse theme

This separates the gathering of file status, repository status and
stash.

Now uses 12-hour clock or 24-hour clock depending
on user locale

$CARETCOLOR was not to actually colour the caret, so change to root user
wouldn't show in the prompt. Now both ▶ and ◀ follow $CARETCOLOR.

Make some colours in the avit theme bold for better visibility in the
default Ubuntu terminal theme.

In commit 729fd53 I incorrectly only changed PROMPT1. Now both ▶ and ◀ follow $CARETCOLOR.

oh-my-zsh avit theme: instead of only showing the last 3 directories in the $PWD shorten the path by removing some middle parts if $PWD becomes too long.

Fix in avit theme: $CARETCOLOR was not to actually colour the caret, so change to root user wouldn't show in the prompt.

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.

Actually replace the value of the environment variable $HOME with
"~" instead of appending the tilde in front of the prompt.

When the current path is /home/user/.config/doublecmd the prompt
now reads "/h/u/.c/doublecmd", not "/h/u/./doublecmd" as was the
case. This matches what the Fish shell does.

Enclose the Perl snippet in single quotes instead of double quotes.

I noticed that for certain projects with unstaged changed I would get a 'U' character instead of the '●' character. This should fix that.

Fix «rvm» variable usage in RPROMPT out

Switch to normal zsh %F/%f prompt escapes to avoid "eval" and extra variables.
Wrap whole thing in anonymous function so the existing `local`
statements actually work. Then switch '...' to eager "..." so
stuff actually works with local variables. And local-ize the
remaining variables that are used only in prompt construction.

- When the previous command's return status is non-zero and the prompt
  is redrawn, graphical errors sometimes arise due to the fg{red} not
  being escaped.

Problem

On detached-refs, the git prompt is very slow because it uses a command
to output all refs, which takes 32s on the twitter internal git repo.

Solution

Use git-rev-parse instead of git-show-ref to only output the head ref.
Runtime drops to 0.03 seconds.

Note

Interestingly, git-rev-parse isn't slow without the --head arguement so
I'll probably be cooking up a patch for the git team to speed this up
eventually, but it's still pointless to sigpipe git as it walks the
filesystem.
