just playing around, it seems to me like julia is escaping with slashes. i
don't have imagmagick installed, but with echo it woks as expected:
julia> run(`echo \(`)
(
julia> run(`echo \\(`)
\(
julia> ^D
andrew@netbook:~> echo (
bash: syntax error near unexpected token `newline'
andrew@netbook:~> echo \(
(
andrew@netbook:~> echo \\(
bash: syntax error near unexpected token `('
andrew@netbook:~> echo \\\(
\(
the two julia commands give results equivalent to `\(` and `\\\(` in bash.
