status: avoid recursing into ignored directory with "--terse u"
Let "isignoreddir" function first check that supplied directory is itself
ignored before walking recursively into its content. Otherwise, the command is
awfully slow when one has an ignored directory with a lot of content.
Update and rephrase function docstring accordingly.
