git add -i: Fix parsing of abbreviated hunk headers
The unified diff format allows one-line ranges to be abbreviated
by omiting the size. The hunk header "@@ -10,1 +10,1 @@" can be
expressed as "@@ -10 +10 @@", but this wasn't properly parsed in
all cases.
Such abbreviated hunk headers are generated when a one-line change
(add, remove or modify) appears without context; for example
because the file is a one-liner itself or because GIT_DIFF_OPTS
was set to '-u0'. If the user then runs 'git add -i' and enters
the 'patch' command for that file, perl complains about undefined
variables.
