מדיה ויקי:Gadget-browsertab.js: הבדלים בין גרסאות בדף

/*
This gadget shortens the tab browser title.
For example,
"(1) אורי צבי גרינברג - הבדלי גרסאות"
יהפוך להיות
"(1) =אורי צבי גרינברג — השוואה"
To understand RTL, the translated result is
"(1) =PageName — diff".
The structure of the new title includes:
1) Browser number data, as "(1)", if existed in the original title.
2) Action symbol, "=" for diff, "^" for editing, "!" for history, nothing for reading.
3) Page name with shortened namespace.
4) Text " — "
5) Action full name, like "ויקיפדיה" for reading, "השוואה", "עריכה", "היסטוריה".
There is no change for two different pages comparing.
