Gnuplot 4.4.2 (fixes some problems with 4.4.1)

[sfeam (E. Merritt) <eam...@gm...>]

I have just uploaded to SourceForge a source tarball and documentation for 
Gnuplot version 4.4.2.

Yes, this follows version 4.4.1 very quickly.  
It fixes three problems that were reported immediately after the 4.4.1
release. Two of these seemed serious enough to justify an immediate fix.

1) The color specification syntax "lc N" was broken in 4.4.1.
   This was a regression from 4.4.0

2) A "refresh" command either from the command line or implicitly from
   mousing would cause a segfault if a previous "replot" command had
   been interrupted.

3) There was an error in the clipping of filled curves when a single
   polygonal fill segment straddled one corner of the plot box.


My apologies for missing a report from Christoph Junghans that pointed
out the "lc N" regression before 4.4.1 was actually released.  
Also my apologies to Tatsuro Matsuoka, whose Windows binaries for
4.4.1 are now out of date only a few days after they were announced.
