Subject: Allow extra commas in filter-specific options on xz command line.
X-Git-Tag: upstream/5.1.3~488
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a35755c5de808df027675688855d1b621a4fb428;p=platform%2Fupstream%2Fxz.git

Allow extra commas in filter-specific options on xz command line.

This may slightly ease writing scripts that construct
filter-specific option strings dynamically.
