Subject: Show output of compression program to stdout, not stderr
X-Git-Url: https://arthur.barton.de/gitweb/?p=MkMySqlDump.git;a=commitdiff_plain;h=b8e78c656a4085d61899609d958341167dfbf81c

Show output of compression program to stdout, not stderr

Some compression programs show their status output on stderr [xz(1),
for example], so redirect to stdout and display an extra error message
when the compression program exited "non zero".

This enhances the user experience when using some "mail wrapper"
scripts etc.
