it automaticalle replaces lastmod with an actual date and time
but removes the possibility to select hunks (did not work properly
anyway)
JUST DONT SELECT HUNKS FOR COMMITS AS THE WHOLE FILE WILL BE COMMITED
AGAIN!
Whenever I want to commit only some hunks of a file, this always
commited the full file when it updated the lastmod frontmatter of
changed files.
making different commits for unrelated changes impossible (but it always
held the lastmod date as accurate as possible)
hope this helps
