[bug-gv] "gv -watch" does not re-render picture on file change

[elmar]

Dear Jose,

I managed to compile gv 3.6.1 under sparc-solaris 2.9 (gcc 3.4.4)
-- I've found a libgnugetopt.a in /usr/local/lib that kept me going.

Now there's an annoying bug which is also present in the 3.5 version:

Starting gv with the -watch option, and then changing the displayed 
encapsulated postscript file
clears the screen, but does not rerender the file. Only after pressing 
'File->Update', 'Reload' 
or Return, the changes are displayed. It seems that the whole reload logic is a 
little dumb:
Pressing "Reload" once just clears the screen ...

Best regards,
