[PATCH 00/14] Restructure the _update member of GitBranch

[Dirk Wallenstein <halsmit t-online de>]

There are a lot of things happening inside _update, and I hope this
series simplifies that a bit. The previous behavior is mostly kept,
except in locations where I thought, that it could be improved: 
- Use '--ignore-submodules' to prevent commits in submodules to trigger
  a stashing operation.
- (return to a) pull after the branch switch, but ensure a recently
  added branch is found when switching
- Fail when there is an attempt to switch dirty branches. Uncommited
  changes on the same branch are still moved along. 

Dirk Wallenstein (14):
  [git] Introduce a predicate execution wrapper
  [git] Rewrite the branch name getter
  [git] Make git version checks more readable
  [git] Use a new predicate to test if a branch tracks a remote branch
  [git] Use a new predicate to determine the need to stash
  [git] Rename would_be_branch to wanted_branch
  [git] Extract the branch switch into a function
  [git] Try to find requested branch remotely if not available
  [git] Switch branches previous to stash and pull
  [git] Extract the pull operation into a function
  [git] Move the quiet option to its point of use
  [git] Extract sticky date operation into a function
  [git] Align local branch predicate with other predicates
  [git] Clarify branch switch destination calculation
