I was going to review this, but can't find what it's based on, I can't
apply 1/4 to master, next or pu. It seems to be based on some older
version of master, e.g. 1/4 has this hunk:

    +			elsif ($line =~ /^l/) {
    +				unless ($other =~ /l/) {
    +					error_msg __("Cannot select line by line\n");
    +					next;
    +				}
    +				my $newhunk = select_lines_loop($hunk[$ix]);
    +				if ($newhunk) {
    +					splice @hunk, $ix, 1, $newhunk;
    +				} else {
    +					next;
    +				}
    +			}
     			elsif ($other =~ /s/ && $line =~ /^s/) {

Which seems to conflict with your 4bdd6e7ce3 ("add -p: improve error
messages", 2018-02-13). I could have tried to manually apply this, but
figured I'd bounce this back to you...

Having just skimmed through the patches themselves I agree with this
approach of handling the simple case (as discussed before) and leaving
the rest for some future change, but let's see about the details once I
have this running.
