Subject: r510:    * Thanks to Benjamin Drieu <benj@debian.org>, dh_installdocs -X now works.
X-Git-Tag: version_2.0.101~89
X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=5221e81cc5f195b32758617409cdc39e12277b82;p=debhelper.git

r510:    * Thanks to Benjamin Drieu <benj@debian.org>, dh_installdocs -X now works.
     I had to modify his patch to use cp --parents, since -P spews warnings
     now. Also, I made it continue to use cp -a if nothing is excluded,
     which is both faster, and means this patch is less likely to break
     anything if it turns out to be buggy. Also, stylistic changes.
     Closes: #40649
   * Implemented -X for dh_installexamples as well.
   * dh_clean -X substvars will also work now. Closes: #66890
