Description

Our release-scripts support/tag.sh & support/vote.sh both fail entirely due to their way of initializing the terminal.
Specifically the included support/colors.sh script's line:

 BLINK=$(tput blink)

When changing the initializing to allow for better debugging set -e -x the resulting trace makes the problem apparent:

$ ./support/tag.sh 1.1.0 2
++ dirname ./support/tag.sh
+ . ./support/atexit.sh
++ declare -a __atexit_cmds
++ dirname ./support/tag.sh
+ . ./support/colors.sh
++ test -t 1
+++ tput colors
++ NUM_COLORS=8
++ test -n 8
++ test 8 -ge 8
+++ tput sgr0
++ NORMAL=''
+++ tput bold
++ BOLD=''
+++ tput smul
++ UNDERLINE=''
+++ tput smso
++ REVERSE=''
+++ tput blink
++ BLINK=

My terminal (iTerm2 with xterm-color256) apparently does not support blinking this way.

$ tput blink
$ echo $?
