Subject: gitk: add menu item for editing the current view
X-Git-Tag: v1.4.0-rc1~21^2~11^2
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=d16c0812a9472794175b2543c2aa2df45a927202;p=git.git

gitk: add menu item for editing the current view

permanent, and the list of files/directories for the view.
