[ccronix]

Rez version after 2.112.0 can not correctly parsing commandline with multiple nested quote escape.

Environment

• OS Ubuntu 20.04
• Rez version 2.112.0 - latest
• Rez python version 3.8

To Reproduce
execute a simple command line: rez-env -- eval "eval \"echo \\\"Hello World\\\"\""

Expected behavior
rez environment will launched and print out "Hello World"

Actual behavior
shell got these error:
/tmp/rez_context_kkcdbkat/rez-shell.sh: line 8: unexpected EOF while looking for matching `''
/tmp/rez_context_kkcdbkat/rez-shell.sh: line 10: syntax error: unexpected end of file

@ccronix dors it work if you unnest a litt bit like:

rez-env -- eval 'eval "echo \\"Hello World\\""'

?
