cover git gui: fix staging a second line to a 1-line file

Yet another patch that is carried in Git for Windows for quite a long time. This fixes https://github.com/git-for-windows/git/issues/515.

This commit was contributed as https://github.com/patthoyts/git/gui/pull/7
which was ignored for almost three years, and then as
https://github.com/prati0100/git-gui/pull/1 which was rejected in favor of a mailing list-centric workflow.

The patch is based on Git GUI's master branch at
https://github.com/prati0100/git-gui/.

PATCH 1/1 git gui: fix staging a second line to a 1-line file

From: Johannes Schindelin <[email protected]>

When a 1-line file is augmented by a second line, and the user tries to stage that single line via the "Stage Line" context menu item, we do not want to see "apply: corrupt patch at line 5".

The reason for this error was that the hunk header looks like this:

	@@ -1 +1,2 @@

but the existing code expects the original range always to contain a comma. This problem is easily fixed by cutting the string "1 +1,2" (that Git GUI formerly mistook for the starting line) at the space.

This fixes https://github.com/git-for-windows/git/issues/515

Yes, this was recently merged in when I was pulling in some stuff that went directly into git.git's git-gui subtree, instead of making it into git-gui first (thread at [0] in case someone wants to find out more). This commit was one of those. Junio directly merged this commit into git/git-gui, along with some other stuff from Johannes in the commit 02a5f25d95 (Merge branch 'js/misc-git-gui-stuff' of ../git-gui) of git.git.

Sorry, I thought I had rebased, but I obviously failed to do so.

Ciao,
Johannes
