+ + add a section to tput manual page clarifying how it determines the
+ terminal size (prompted by discussion with Grant Jenks).
+ + add "--disable-relink" to rpm test-packages, for consistency with the
+ deb test-packages.
+ + split spec-file into ncurses6.spec and ncursest6.spec to work around
+ toolset breakage in Fedora 28.
+ + drop mention of "--disable-touching", which was not in the final
+ 20180818 updates.
+
+20180818
+ + build-fix for PDCurses with ncurses-examples.
+ + improved CF_CC_ENV_FLAGS.
+ + modify configure scripts to reduce relinking/ranlib during library
+ install (Debian #903790):
+ + use "install -p" when available, to avoid need for ranlib of
+ static libraries.
+ + modify scripts which use "--disable-relink" to add a 1-second
+ sleep to work around tools which use whole-second timestamps, e.g.,
+ in utime() rather than the actual file system resolution.
+
+20180804
+ + improve logic for clear with E3 extension, in case the terminal
+ scrolls content onto its saved-lines before actually clearing
+ the display, by clearing the saved-lines after clearing the
+ display (report/patch by Nicholas Marriott).
