Subject: xz: Check if the file already has custom suffix when compressing.
X-Git-Url: http://repo.or.cz/w/xz.git/commitdiff_plain/8930c7ae3f82bdae15aa129f01de08be23d7e8d7
xz: Check if the file already has custom suffix when compressing.
Now "xz -S .test foo.test" refuses to compress the
file because it already has the suffix .test. The man
page had it documented this way already.

xz: Clean up suffix.c.
struct suffix_pair isn't needed in compresed_name()
so get rid of it there.
