As Sarah said, Rev won't wrap these lines. If your field has no tab 
stops in it, you can use a cheat. Set the tabstops of the field to 1. 
Then use this in your handler:

   replace slash with slash&tab in fld 1

Visually it looks almost right, you have to really squint to see those 
1-character tabs. This way the engine will wrap the line automatically. 
If you only want to wrap a single line in the field, just use something 
like:

   replace slash with slash&tab in line x of fld 1

If you need to use the URL for something, be sure to replace tab with 
empty in the field contents before using it for anything:

   get line x of fld 1
   replace tab with empty in it
   launch url it -- or whatever

If you need real, hard-coded carriage returns or you can't set the 
tabstops to 1, this handler works on longer URLs that need to wrap over 
more than 2 lines. (Sarah's works fine on 2-line wraps.)

on wrapField pFld -- pass name or number
   set the itemdel to slash
   put the width of fld pFld - (the leftmargin of fld pFld) - (the \
      rightmargin of fld pFld) into tWidth
   put 1 into x
   repeat until the formattedwidth of fld pFld <= tWidth
     if the formattedwidth of item 1 to x of fld pFld > tWidth then
       put item 1 to x-1 of fld pFld & slash & cr after tText
       delete item 1 to x-1 of fld pFld
       put 1 into x
     else
       add 1 to x
     end if
   end repeat
   put tText & fld pFld into fld pFld
end wrapField
