An ideal solution would simply convert the .webloc files to .url files. I am still looking for such a solution, in the meantime, a trick I found here works well:
Open Textedit, click and drag .webloc files or URL (from Safari) into document, an Http link is formed. Press right arrow key to go to end of line, then press Return twice. Repeat.
You can save as many links as you like, or open up the file later and add more links. Save it as a .rtf document (default) and it can be used in Windows or Mac.
