[aur-general] Incorrect name when downloading from source=()

Hello, To package cellwriter, I need to download this patch[1]. But once downloaded, the name of the file is "attachment?aid=-5287197620305474653&name=cellwriter-1.3.4-cellwidget-dont-disable-xinput.diff" instead of just "cellwriter-1.3.4-cellwidget-dont-disable-xinput.diff". - Is it a big problem ? I mean if another user do not use wget will my PKGBUILD work for him ? - Is there a way to force a correct behavior ?
