Undesired newline at the end of command metadata

[aivarsV]

Like title says, in latest version, command metadata ends with \n character. This might not be an issue, if using passing {2} as the last argument to launch command as in example from README.MD. But it will fail to launch desktop entries with extra arguments, if {2} is used in the middle of launch_cmd, like following:

[desktop]
list_cmd=sway-launcher-desktop list-entries
preview_cmd=sway-launcher-desktop describe-desktop "{1}"
launch_cmd=riverctl spawn "$(sway-launcher-desktop generate-command '{1}' '{2}' | sed -e 's/^exec //')"

For me, quick and dirty solution was to remove any new lined from COMMAND just before it is executed:

diff --git a/tmp/sway-launcher-desktop.sh b/usr/bin/sway-launcher-desktop
old mode 100644
new mode 100755
index 6c0ba38..c684a2c
--- a/tmp/sway-launcher-desktop.sh
+++ b/usr/bin/sway-launcher-desktop
@@ -363,6 +363,7 @@ readarray -d ${DEL} -t PROVIDER_ARGS <<<${PROVIDERS[${PARAMS[1]}]}
 COMMAND=${PROVIDER_ARGS[2]//\{1\}/${PARAMS[0]}}
 COMMAND=${COMMAND//\{2\}/${PARAMS[3]}}
 COMMAND=${COMMAND%%[[:space:]]}
+COMMAND=${COMMAND//[$'\n']}
 
 if [ -t 1 ]; then
   echo "Launching command: ${COMMAND}" >&3

However, I believe, undesired newline comes from

sway-launcher-desktop/sway-launcher-desktop.sh

Line 331 in f19bbb8

COMMAND_STR=$(printf '%s\n' "${COMMAND_STR[@]: -1}")

Seems to affect describe-command as well, test fails for ls
