[PATCH 0/2] gitk: fix --full-diff handling

[Felipe Contreras]

Hi,

I find usel to do 'git log --full-duff -- file' to find out all the commits
that touched the file, and show the full diff (not just the one of the file).

Unfortunately gitk doesn't honour this option; the diff is limited in the UI.

The following patches fix that.

[PATCH 1/2] gitk: simplify file filtering

[Felipe Contreras]

git diff is perfectly able to do this with '-- files', no need for
manual filtering.

Otherwise the files are missing from the diff, and the list of files.

There is Edit->Preferences->General->Limit diff to listed paths. Doesn't
it do what you want if you switch it off?

Hmm, I guess so, but it's not triggered from the command line. Maybe
the --full-diff option should enable that flag.
