From: Phillip Wood <phillip.w...@dunelm.org.uk> Since v2 I've updated the patches to use '-' instead of '^' to invert the selection to match the rest of add -i and clean -i.
These patches build on top of the recount fixes in [1]. The commit message for the first patch describes the motivation: "When I end up editing hunks it is almost always because I want to stage a subset of the lines in the hunk. Doing this by editing the hunk is inconvenient and error prone (especially so if the patch is going to be reversed before being applied). Instead offer an option for add -p to stage individual lines. When the user presses 'l' the hunk is redrawn with labels by the insertions and deletions and they are prompted to enter a list of the lines they wish to stage. Ranges of lines may be specified using 'a-b' where either 'a' or 'b' may be omitted to mean all lines from 'a' to the end of the hunk or all lines from 1 upto and including 'b'."
