Con Kolivas	920ad9251d	Make open use mode 0777 since it will already be & ~umask it will preserve the default permissions. ... Don't try to copy permissions from STDIN.	2011-04-10 11:03:45 +10:00

Con Kolivas	b27e1df879	Revert "Modify the file format to not include rzip chunk size except for STDOUT chunked files thus decreasing the file format size further." ... This reverts commit 131d4c92c2.

Con Kolivas	8077412ee5	Allow files with non-standard extensions to be tested or decompressed if they actually exist. ... Don't allow a suffix if an actual output filename has been specified. Convert ints to chars when they can be.	2011-03-23 01:51:40 +11:00
