agnoster: cut down on fork/execs improve performance when not in a repo (#6210)
* agnoster: improve perf with use of $jobstates (zsh/parameter module) This saves multiple fork/execs (for the subshell and wc) each time the prompt is rendered * agnoster: compute git repo_path only when in a git repo this avoids needlessly invoking git twice every time we render the prompt * agnoster: avoid subshell when rendering prompt Rather than forking a subshell to print the prompt, construct it incrementally by appending to $PROMPT. v2: fix incorrect CURRENT_BG v3: fix bzr and hg prompting Thanks @mcornella for the help.
