worktree: don't use C99 feature

Commits 9c0b9f6 ("worktree: add 'list' command", 18-09-2015) and 40ca3d3 ("worktree: add functions to get worktree details", 18-08-2015) both introduce the use of a C99 feature (declare the loop control variable in the loop header initializer section).

Hi Junio,

The pu branch doesn't build for me. Do you have -std=c99 set somewhere?

Could you please squash the relevant parts of this patch (or something like it) into the two commits mentioned above.

Thanks!

ATB,
Ramsay Jones
