 Summary of the bug:
 The parser for filters seems to be broken or incomplete, because it
 doesn't correctly interpret some cases, for example:
 {{{
 -vf select='not(mod(n,100))'
 }}}
 has to be written like:
 {{{
 -vf select='not(mod(n\,100))'
 }}}
 I guess this is a workaround to solve some problematic parsing problems or
 something, but imho it should be fixed rather than be ignored or even
 moved to documentation as such.

 A comma character does not need to be escaped, since it is inside the
 parenthesis, and it is obvious that it can't be a delimiter for another
 filter in the chain.
