[slang-users] two small slang2 patches

["John E. Davis" <davis@xxxxxxxxxxxxx>]

Hi,

So far there have been no significant problems reported.
Nevertheless,  here are a couple of patches that fix a couple of
problems that I discovered.

The first patch is to modules/png.sl.  An assignment to 'gray' was
missing from the png_gray_to_rgb function.  The second patch is to
slsh/lib/print.sl.  It causes SIGPIPE to be ignored while in the
pager.

Thanks,
--John
