[patch] Fix VCS_INFO_reposub's whitespace handling

[Marco Hinz <mh.codebro@xxxxxxxxx>]

Hi,

VCS_INFO_reposub is the function called to process VCS_INFO's %S flag
in 'formats' and 'actionformats'.

Problem:

$ mkdir -p '/tmp/foo   bar'
$ cd !$
$ VCS_INFO_reposub

Output:

"tmp/foobar" instead of "tmp/foo   bar".

I'm new to zsh internals, but apparently something causes the string
'foo   bar' to be read in as 2 arguments. printf only takes 1
argument, and so 'bar' just gets appended.

Could someone point me to the appropriate parameter expansion rule?

Solution:

Double-quote ${$(pwd -P)#$base/}.

Regards,

Marco
