Merge branch 'precheck'

Provide an additional entrypoint 'git-precheck', a new script intended
for use by other git-related scripts to determine the initial state of a
repository before continuing to do additional work.

git-sonar now leverages some of the information returned by git-precheck
to update its "is inside git repository" check, as well as provide a new
prompt string feature which visualizes on the prompt whether a merge,
rebase, etc. is in progress.

* precheck:
  Add new prompt output element "condition"
  Use git-precheck to determine if we are inside a repository
  Add git-precheck script
