These should be pretty obvious and straightforward.

This is exactly the same as v3, which alread included the minor adjustment to the commit message of one patch, but for some reason v3 had trouble getting into 'seen'. So I'm sending it again as a new thread.

Felipe Contreras (4):
  completion: bash: fix prefix detection in branch.*
  completion: bash: fix for suboptions with value
  completion: bash: fix for multiple dash commands
  completion: bash: add correct suffix in variables

[PATCH v4 1/4] completion: bash: fix prefix detection in branch.*

Otherwise we are completely ignoring the --cur argument.

The issue can be tested with:

  git clone --config=branch.<tab>

[PATCH v4 2/4] completion: bash: fix for suboptions with value

We need to ignore options that don't start with -- as well.

Depending on the value of COMP_WORDBREAKS the last word could be duplicated otherwise.

Can be tested with:

  git merge -X diff-algorithm=<tab>

[PATCH v4 3/4] completion: bash: fix for multiple dash commands

Otherwise options of commands like 'for-each-ref' are not completed.

[PATCH v4 4/4] completion: bash: add correct suffix in variables

__gitcomp automatically adds a suffix, but __gitcomp_nl and others don't, we need to specify a space by default.

Can be tested with:

  git config branch.autoSetupMe<tab>

This fix only works for versions of bash greater than 4.0, before that "local sfx" creates an empty string, therefore the unset expansion doesn't work. The same happens in zsh.

Therefore we don't add the test for that for now.

The correct fix for all shells requires semantic changes in __gitcomp, but that can be done later.
