failure when searching by complete filename with -P and --color=always options

[William Xu]

Hi,

I find a nasty bug that when searching a filename with its complete
path, together with -P and --color=always options, the returned file
path is incorrect, missing a "../" at the front.  Below is steps for
reproducing.

version: global (GNU GLOBAL) 6.5.2
OS: Mac OS 10.11.2

---------------------------------8<------------------------------------- 
$ tree .
.
|-- GPATH
|-- GRTAGS
|-- GTAGS
`-- hi
    |-- bar.cpp
    |-- foo.cpp
    `-- what

2 directories, 5 files

$ cd hi/what
$ global -P --color=always  foo.cpp
../foo.cpp

$ global -P --color=always  hi/foo.cpp
foo.cpp
^^^^^^^ (this is wrong!!)

$ global -P   hi/foo.cpp
../foo.cpp
---------------------------------8<-------------------------------------
