[PATCH 2/3] vcs_info git: Make sure applied-patches is of the form "$hash $subject" --- that is, has a space and a non-empty second argument --- even with future 'git rebase -i' verbs.

[Daniel Shahaf <d.s@daniel.shahaf.name>]

Use of '?' is consistent with these precedents:

Backends/VCS_INFO_get_data_git:220:            printf -v "git_patches_applied[$p]"  "%04d ?" "$p"
Backends/VCS_INFO_get_data_git:242:                git_patches_applied+=("? $subject")
Backends/VCS_INFO_get_data_git:244:                git_patches_applied+=("?")
VCS_INFO_quilt:160:            applied[$i]+=" ?"
VCS_INFO_quilt:168:            unapplied[$i]+=" ?"
