+ (report/testcase by "puppet-meteor").
+ + use a more conservative estimate of the buffer-size in lib_tparm.c's
+ save_text() and save_number(), in case the sprintf() function
+ passes-through unexpected characters from a format specifier
+ (report/testcase by "puppet-meteor").
+ + add a check for end-of-string in cvtchar to handle a malformed
+ string in infotocap (report/testcase by "puppet-meteor").
