If you run git diff for a pathspec with an empty magic word/symbol
list in short form (prefixed by ::) and in long form (prefixed by
:():), you get different results.
The short form is prefixed by a ":" and optionally ends by a ":",
but the optional termination may not be required when there is no
ambiguity (e.g. ":/!path" is "from the top, not matching "path", as
"p" cannot be a magic signature; ":/:!path" is "from the top,
matching "!path", as the set of magic signatures ends with the
second disambiguating colon).
The long form is prefixed by a ":(" and ends by a ")".
Here’s an example use of git that illustrates this:
~☭ mkdir gittest
~☭ y gittest/
~/gittest☭ git init
Initialized empty Git repository in /home/anselmschueler/gittest/.git/
~/gittest (b0)☭ uuidgen >file
~/gittest (b0)☭ git add file && git commit -m "$(read)"
read> initial commit
[b0 (root-commit) cd3bd43] initial commit
1 file changed, 1 insertion(+)
create mode 100644 file
~/gittest (b0)☭ uuidgen >file
~/gittest (b0)☭ git diff -- "::file"
file

~/gittest (b0)☭ git diff -- ":():file"
~/gittest (b0)☭
Doesn't ":():file" ask for a match for the pattern ":file", with a
leading colon?
