Try this syntax in forEachTiddler:
"+tiddler.tags.join(", ")+"
Here's what it does:
tiddler.tags refers to an *array* of individual tag values. By
default, when an array is referenced as part of constructing a text
string (which is what forEachTiddler syntax is doing), it produces
comma-separated output without any extra spaces (as you've noted)
(e.g, an array of tags [a,b,c], produces text output "a,b,c").
Fortunately, you can achieve the output you want by using
the .join("...") method, which allows you to specify the desired
"separator text" to construct the intended text output from the n
array of values. The separator you provide is automatically inserted
between array values to create a single combined text string. Thus:
if tags contains [a,b,c], then
tiddler.tags.join(", ")
will create a single text string:
"a, b, c"
which is exactly what you want.
