From 4bf72cb8f1d3aa5f33c31eb817a5f0338f4aaf6f Mon Sep 17 00:00:00 2001

Subject: [PATCH] Import upstream patch 20170826
20170826
+ fixes for "iterm2" (report by Leonardo Brondani Schenkel) -TD
+ corrected a warning from tic about keys which are the same, to skip
over missing/cancelled values.
+ add check in tic for unnecessary use of "2" to denote a shifted
special key.
+ improve checks in trim_sgr0, comp_parse.c and parse_entry.c, for
cancelled string capabilities.
+ add check in _nc_parse_entry() for invalid entry name, setting the
name to "invalid" to avoid problems storing entries.
+ add/improve checks in tic's parser to address invalid input
+ add a check in comp_scan.c to handle the special case where a
nontext file ending with a NUL rather than newline is given to tic
as input (Redhat #1484274).
+ allow for cancelled capabilities in _nc_save_str (Redhat #1484276).
+ add validity checks for "use=" target in _nc_parse_entry (Redhat
#1484284).
+ check for invalid strings in postprocess_termcap (Redhat #1484285)
+ reset secondary pointers on EOF in next_char() (Redhat #1484287).
+ guard _nc_safe_strcpy() and _nc_safe_strcat() against calls using
cancelled strings (Redhat #1484291).
+ correct typo in curs_memleaks.3x (Sven Joachim).
+ improve test/configure checks for some curses variants not based on
X/Open Curses.
+ add options for test/configure to disable checks for form, menu and
panel libraries.
