Different shells have different errors. On my system the above gives:

sh: Syntax error: Unterminated quoted string

I got the same with bash version 4.1.5

With bash version 4.0.35 I get:
sh: -c: line 0: unexpected EOF while looking for matching `''
sh: -c: line 1: syntax error: unexpected end of file

That is odd: -q works for me:

Me too. "parallel -q" works well with Bash version 4.0.35.

Not the 4.1.5 version.

$ ls NEWS | parallel -q grep "'"
  sem 'sleep 2; echo foo'; sem 'sleep 1; echo bar'; sem --wait
  sem -j2 'sleep 2; echo foo'; sem -j2 'sleep 1; echo bar'; sem --wait
  cat tab_sep_table | parallel --colsep '\t' echo col1 {1} col2 {2}
* --sshloginfile '..' means use ~/.parallel/sshloginfile

$ ls NEWS | parallel -q -tp grep "'"
grep \' NEWS ?...
