Global --match-part option

[Pavel Nedev]

Hi,

First I'd like to thank you for the great tool you have created. As a C/C++ 
developer I'm using it extensively and I find it really, really helpful.
I have created plugin for Notepad++ that is a front-end to GTags (Win32 port) 
and during its testing I noticed that global --match-part option doesn't seem 
to work.
I also tried it with the native global binary (6.3.3 on Linux) but the behavior 
is the same.
It appears that --match-part option does not have any effect on the command 
output.
For example, I'm running

global --match-part first -cPM int

and it has exactly the same output as

global --match-part all -cPM int

That is, it outputs files that match "int" in the middle of the name. 
--match-part last also doesn't have any effect.

Thank you and Best Regards,
Pavel
