Global autocomplete filename issue

[Pavel Nedev]

Hi guys,

First, thanks for the great software! I'm using it extensively and it is of 
great help indeed.

As to the issue:
I notice that the autocomplete filename command returns as result not the full 
names but from the matched string to the end of the name.
For example if you do

1) global -cP string

you would expect to get the file names containing the string.
I know that -P by default searches the whole file name for the string, not just 
from the beginning. And this is working fine in

2) global -P string

for example. The whole file names are returned as result by 2). But 1) does not 
do that.

Consider the following scenario:
You have the following files:

src/first_string_A.cpp
first_string_A.h
test/sec_string_A.cpp
string_C.h
text.cpp

Now command 2) (global -P string) result would be

src/first_string_A.cpp
first_string_A.h
test/sec_string_A.cpp
string_C.h

But command 1) (global -cP string) would give

string_A.cpp
string_A.h
string_A.cpp
string_C.h

IMO it should either run the completion from file name beginning or return the 
full file names as 2) does

Thanks again!
