Hello,

I think I found a bug in Functions/Misc/regexp-replace

Steps to reproduce:

zsh -f

str='x :=bad'

autoload regexp-replace

regexp-replace str 'a' 'z' && echo $str

Actual Output:

(eval):1: bzd not found

Expected:

x :=bzd

Root cause:

Line 41: eval ${1}=${(q)5}

It appears the ${(q)5} is not escaping = so the =command is executed after :

Instead of 'x\ :\=bad', you get '= x\ :=bad'

One way to fix:

41: eval ${1}=${(qqq)5}

Patch file is attached.

Thanks

Jacob Menke
