Re: git diff: hunk header config

[Michael Brand <michael.ch.brand@gmail.com>]

Hi all

1) Since there has been no feedback yet I'd like to bump my previous
post repeated below. I would like to have the config of the repo
orgmode.org/org-mode.git to be extended to support more useful diff
hunk headers containing e. g. the prototype of the current function
for *.el files. Like
"@@ -12991,7 +12991,7 @@ (defun org-align-tags-here (to-col)"
instead of the current
"@@ -12991,7 +12991,7 @@ If ONOFF is `on' or `off', don't toggle but set to thi"
Can this be done in the repo orgmode.org/org-mode.git at all?
Effective for everyone after only git pull?

2) Note: Also a config of git, but for diff of crypted Org files is
shown at the end of this recent post:
