git developers:

Small feature request on: git log --oneline <revision range> -- <path>...

Could we add an option to:
1) display all commits in <revision range> unconditionally
2) use a special marker (e.g. star) for commits that touch <path>...
and list the files from <path>... that this commit modified

Sample output: git log --oneline (--annotated?) HEAD~5..HEAD -- Makefile kernel/printk/printk.c

  aaaabbbbccc1 uninteresting commit 1
* aaaabbbbccc2 fix Makefile
    Makefile
  aaaabbbbccc3 uninteresting commit 2
* aaaabbbbccc4 fix Makefile and printk()
    Makefile
    kernel/printk/printk.c
  aaaabbbbccc5 uninteresting commit 3

In other words:
- commits that don't touch <path>... are still listed (without special markers)
- commits that touch <path>... are listed with * prefix, and the files
from <path>... that the commit modified are listed below the commit

This is very useful for kernel LTS merges, when we want to know which LTS patches in the merge chain actually touched the files that matter for a specific build target.

Is this an easy add-on to git log?
