Subject: add -i: Fix running from a subdirectory
X-Git-Tag: v1.5.4-rc0~77^2~5
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=3f061887c562b20d3ed3d1f764462cf986a1ad12;p=git.git

add -i: Fix running from a subdirectory

This fixes the pathspec interactive_add() passes to the underlying
git-add--interactive helper.  When the command was run from a
subdirectory, cmd_add() already has gone up to the toplevel of the work
tree, and the helper will be spawned from there.  The pathspec given on
the command line from the user needs to be adjusted for this.

This adds "validate_pathspec()" function in the callchain, but it does
not validate yet.  The function can be changed to barf if there are
unmatching pathspec given by the user, but that is not strictly
necessary.
