[BUG][UNIX] Failed to parse command line option with space in filename

[jopadan]

Steps to reproduce:

• get tetrahedron_twist
• run povray wobbles\ -\ tetra\ twist.pov

As a user, I agree it's a bug.

While there are forks where the unix quoting you show will work, in the current official v3.7, v3.8 and v4.0 branches, one must use non-standard quoting as in:

povray "\"thing1 -thing2.pov\""

or something like

povray "Input_File_Name=\"thing1 -thing2.pov\""

where sort of an ini file form is used on the command line. However, in an ini file one would use just:

Input_File_Name="thing1 -thing2.pov"
