Subject: Split a part of getconf into printconf.
X-Git-Url: https://git.stderr.nl/gitweb?p=matthijs%2Fupstream%2Fbackupninja.git;a=commitdiff_plain;h=ecf8ddbe3aee37f5a2b772207b3deea3d952d2cb;hp=ecf8ddbe3aee37f5a2b772207b3deea3d952d2cb

Split a part of getconf into printconf.

The printconf function allows getting a variable without clobbering the
global variable with te same name. This can be used for a per-handler
override of a global variable, e.g. local_foo=`printconf "foo" "$foo"`
