Severity: minor
Tags: patch

I'm working on a large Unity project where some of out scene and prefab
files reach six digit line numbers.  When using git add -p on such a file
and selecting the go to hunk option, these errors appear:

Negative repeat count does nothing at /usr/lib/git-core/git-add--interactive 
line 1399, <STDIN> line 1.

It seems to be due to the summary of the hunks exceeding 20 characters.
The error appears once per such a hunk and makes the list of hunks
difficult to read.  It can be avoided by simply wrapping the offending
line in an if (see attached patch).
