After the editor was closed, adjust the hunk headers and apply the patch to the index. + -*NOTE*: Obviously, if you change anything else than the first character -on lines beginning with a space or a minus, the patch will no longer -apply. +The intent of this option is to pick and choose lines of the patch to +apply, or even to modify the contents of lines to be staged. There are +three line types in a patch: addition lines (beginning with a plus), +removal lines (beginning with a minus), and context lines (beginning +with a space).

Conceptual changes like +modification of a line in the original file are actually represented by +removal of the old line followed by addition of the new line.

In other words, use +this feature with caution, as it is easy to stage unintended changes. -u:: --update:: |
