Dirmngr was designed as a system service, thus the hardwired socket
name.  The whole thing will be changed anyway to be started on demand,
much like gpg-agent.  Thus this patch does not make sense.  Some
comments anyway:

The ChangeLog Entries are mssing; see doc/HACKING.

Please do me a favour and avoid comparsions to NULL. 

     if (existsing) 
       {
       }

is much easier to read and less error prone.  Yes, I know there are
different schools, but in GnuPG this should be used if you remember it.

Please also use GNU indentation style; for master most of the code has
been converted to that style and thus new code should generally be
written in this style.  Well, for a small change of existing old-style
indented code, you would keep the old style.

Please always use xfree instead of free.


Shalom-Salam,
