           Summary: A shell script to rename files, which works perfectly

SUMMARY
I have a shell script to use in Dolphin ServiceMenu, cleaning filenames
particularly for cross-platform compatibility, which runs as expected in
terminal, but when used in a Dolphin ServiceMenu, it leaves a leading space in
filename.

STEPS TO REPRODUCE
1. Run this command in terminal: touch "   a truly <horrible>|"awful"
"$'\n'"name     with a newline and *globs*, and even a 'single' quote or two?! 
 .txt"
2. And then this command: rename 's/[*\n<|>"[\]]/ /g; s/\?//g; s/\\/ /g; s/
,/,/g; s/:/-/g; s/\s+/ /g; s/^\s*//; s/\s+\././g; '"s/'//g" *
3. You will see a clean filename if you run this command: ls -N
4. Enter that command in a shell script file, starting with "for filename in
"${@}"; do" and ending with " "$filename"; done".
5. Add this shell script file to an appropriate ServiceMenu file.
6. Repeat step 1 and then run this script this time from context menu.

OBSERVED RESULT
One leading space is left in filename.

EXPECTED RESULT
No leading space should be left as in terminal.
