I would be happy to take a look at the discussion.
IMHO a good solution is to use '\ ' to escape spaces. It is standard 
Unix approach.
The real '\' character should be passed as double '\' ("\\").
What is nice, it works just great in "-file-exec-and-symbols" command, 
so it seems
a pretty straight forward solution to make other commands consistent 
with this one.

Unfortunately this does not work:

break 'C:/Documents and Settings/nikm/.netbeans/Netbeans 
Projects/Args1/src/main.c':17
&"break 'C:/Documents and Settings/nikm/.netbeans/Netbeans 
Projects/Args1/src/main.c':17\n"
&"Function \"C:/Documents and Settings/nikm/.netbeans/Netbeans 
Projects/Args1/src/main.c\" not defined.\n"
~"Breakpoint 3 ('C:/Documents and Settings/nikm/.netbeans/Netbeans 
Projects/Args1/src/main.c':17) pending.\n"
^done
(gdb)

And this one also does not work:

221-break-insert "'C:/Documents and Settings/nikm/.netbeans/Netbeans 
Projects/Args1/src/main.c':17"
&"Function \"C:/Documents and Settings/nikm/.netbeans/Netbeans 
Projects/Args1/src/main.c\" not defined.\n"
221^done
(gdb)
